CCNP ENARSI (300-410) : OSPF

2. 3_2 Multi Area OSPF

Multi-arriospf, which is a way of limiting the amount of neighbours in an area, is also a design option for the OSPF by using multi-oreo SPF. We are having smaller link state databases and routing tables, and we are making rare SPF calculations. This design is suitable as a solution for large networks to decrease processing by over half. As you can see in here, we have multiple areasin here and they are area 50 and the area60 and each area is connected to area zero whichis backbone area by an area border. Rather, each additional area in an OSPF domain must have a connection to the OSPF backbone area, as I told you. And such connections are maintained by an interconnecting router known as an area border router, or ABR. An ABR maintains separate link state databases for each area itself and maintains summarised routes for all areas in the network. For example, if the link between Rather Eight and Rather Nine is down area burger router, which is rather true for this area, default isolation occurs. So just area 50 is affectedfrom failure and makes SPF recalculation. Let's go ahead with the autonomysystem boundary, which is ASPR, an autonomousystem boundary. Rather, it is a router that is connected by using more than one routing protocol and that exchanges routing information with its autonomous system. Asprically also run an exterior running protocol for examplesuch as BGP or use static routes or both. An ASPR is used to distribute routes received from other external autonomies through its own autonom system.And here are the OSPF LSA types. We have seven types of the OSPF LSS. The first LSA type is the router LSA, and this LSA is generated by Dr to describe the neighbours connected to that segment. The third and fourth LSAs are the summary LSAs, and these guys are generated by ABR to describe errors to ASPR for neighbours outside the area. Type 5 LLC is the external LLC, and they are generated by ASPR to describe routes to redistribute it into the area. The 6th is the multicast LSA, which is used in multicast OSPF, and this is not supported in Cisco devices. And the selling LSA type selling is theNSSA external LSA not so stubby area andgenerated by an ASP are inside NSSA areato describe routes redistributed in the Notsobby area. Let's go ahead with the OSPF routing table review. As you can see in here, to display the OSPF rods for the router 4, we are typing show IP rods and the OSPF command, and we have some entries in here. As you can see, we have some keywords, which are IA or some letters like O in here, and they mean O means, for example, the SPFIA means the inter array, and we can also see the E one and E two as you can see in here. And these guys are the externalroutes redistributed into the area. Let's go ahead with the OSPF router summarization. In an OSPF design, just ABR and ASPRrouters can summarise the route skies. Introduction and, as I told you, ABS can summarise the routes between Backbone and the other areas. And as you can see as an example, in here we have two separate networks, which are 1041-10 and 104120-24, as you can see in here. And router two, for example, which is an AVR, is representing these routes by using a single route, which is 1000 and 4122. ASPRS can also summarise in OSPF 2, and ASPRS can summarise many external routes into one link state to configure multi-OSPF. We are using these commands as you can see here. For example, on router two, to configure OSPF, we are typing router OSPF and the process number and hitting the enter key. Then we are in the config router mode anymore. The first thing we should do is define our router ID. First, we are defining a router ID. Please pay attention and remember that, as I explained to you on our previous slide, this is not an IP address or something like that. We are mostly defining our router ID mostly.We are defining these guys similarly to our router names. For two, we can mostly use "two two," but that is arbitrary. But in most cases, we are using it like that. And then in the third step, we are defining our network statements. For example, this guy is rather closely connected to these two networks. As you can see, we have two networks, which you can see here. And we are defining these network statements. For example, consider network ten (41,500) with a wildcard mask of Europe (255).Because if we are using 24, which means 255-255-2550, and if I convert this to the wildcard mask, that's the wildcard mask of the subnet mask zero, zero F, and this network belonging to the area 15, area 50. I'm sorry. And I'm typing in area 50 with the same logic. As you can see, we have another network connected to router two. This network is in array zero, and we are typing network with the network ID 1041 260. And because we are using 24, the wildcard mask will be 255, and area zero will be the area zero.To configure rod summarization on an ABR, we are using the area range command. For example, for router two, if I want to configure route summarization and if I want to summarise these two guys by using a single network, which is 1041-22, the command I'm using is the area range command. Okay, I'm typing on rather to the area range. Then I'm typing the summarised draught 10410zero with the subnet mascot set to zero. Okay, that makes the summarization for us.

3. 3_3 OSPF Optimization

In our next section we are goingto talk about the OSPF optimization.In the first lesson of OSPF optimization,we will discuss Rat Summarization which wementioned earlier in in more detail.Rod summarization is an important perimeter for scalability inOSPF and helps us solve two important problems.The first problem is large routing tables and thesecond is fractioned LSA fluids through the autonom system.When a route is lost in each area,the routers in the other area are alsorequired to perform the shortest path calculation.Route summarization can be done on the AVR orthe ASPR to reduce the area database size.With Route summarization, ABRs or ASPRS combinemultiple route information into a single route.Rod summarization directly affects bandwidth, CPU powerand memory resources consumed by OSPF routing.With route summarization, only summarized routes are propagatedinto the backbone array which is array zeroand the stability of the network is enhanced.Here is how we can summarize the routes on the ABR.The commands we are using on ABR to summarizethe routes is Area and Area ID and range.This is the more important thing we need to focus.Then we use the IP address and a mask.We are going to take a look on an example too.If you want to summarize on ASPR which israther one for this example, the thing we areusing is the Summary Address command this time.Here, as you can see that we haveroutes on the external Sdomain which is EIGRP.And if you want to summarize these routeson rather one, we are using Summary Addressand the IP Address mask and that's it.And let's take a look tothe OSPF virtual links right now.Normally guys, when designing OSPF, each areamust be associated with area zero.A design like in the figure cannot be donefor OSPF, but if Arias cannot physically connect toeach other, a solution can be used temporarily.In such a case, the route table of RouterThree and Router Phone Four does not see orconnected to the Internet interface of router two.For this, the virtual link between Router Three and RouterTwo is configured as shell, as you can see.Now I figured that's the backbone area oneis directly connected to here, but area twois not directly connected to Pacman area andit's directly connected just to area one.To resolve this problem, we need to useOSP virtual links and the configuration is madeon the router three and router two.We type Router SPF and the process number andwe define the area one, this area which isdirectly connected to ray zero on both routers.Then we type virtual link and theRouter ID of the router three.And if you want to verify the virtuallinks, we can use Show IPSP virtuallinks command.The OSPF Stop and Totally Stop structurewas developed to reduce the size ofthe OSPF database and the routing table.For example on router one if we type show IP route,it can be seen that even the cords from the ripnetwork this guy are in the routing table of rather one.However, Rodber one does not need this route, itonly inflates the routing table of the router one.Normally we can solve this problemwith default route or etc.But our goal is to solve with OSPs.To solve this problem, stubby and totallystubby area configurations must be done.Stubby area this guy blocks type five LSSwhich means LSS from external networks such asRip or Aijr or something like that.And total stubby area blocks thetype three, four and five LSS.And let's check how we can configure the OSPF subarea.Let's take a look to the router threeconfiguration first, the OSPF configuration of router threeis rather OSPF and our process number.Then we advertise our networks and we are usingarea number which is area two and stop.Whenever we type this, the neighborhood between routerthree and router four is downown unless weconfigure the OSPF stop flag on router four.And to configure the OSPF stop on routerfour we are typing the same thing.We just type area number and stop and that's it.And let's take a look to the OSPF totallystubby area configuration to configure a totally setup areaon router tree which is an AVR with typearea area number and this time we type stop.No summary instead of stop but in router fourwe are typing again area number and just stop.And this makes these configurations make area twoas total stubby area and we block thetype 34 and five LSAs in this area.Allows the external routes outside the OSPF autonomoussystem to be advertised in the OSPF autonomyASPR is found in NSSA and external networks.Fluid in NSSA with a The ABR whichcommunicates the NSSA with the other areas doesnot allow the transmission of type seven LSAs.It receives and converts them into type fiveLSAs and transmits them to the other areasallowing the OSPF autonomous system to learn theexternal networks of the other areas.And here is how we canpropagate a default route in OSPF.If you want to propagate a default route inOSPF, we type router SPF and process number.And here is the command for propagatingdefault information and originate propagates a defaultroute to other guys in OSPF domain.

4. LAB - Basic OSPF Configuration

Alright guys, that's lab time again, and we have a basic OSPF configuration lab for you. We have five tasks to complete. We have five routers in our topology and need to configure OSPF for the network above. Okay, here is area zero, here is area ten and here isarea 20, as you can see, rather one should be an ASPR. This guy should be an ASPR, which redistributes the static routes. Okay, these are the static routes, this is an external routing domain, and these routes should not increase their metrics while they are passing over the network and should have a beginning OSPF cost of $200. All right? And all others should have a routerID that is similar to their names. Okay, what is being said here is that we need to redistribute these routes. We are going to talk about redistribution later, and I'm going to show you deeply what redistribution is redistribution.But basically, if you want to communicate between different routing protocols, or between static routing and dynamic routing protocols, you need to use redistribution. Okay? And there are two options for redistributing in the OSPF. If we are redistributing as an EONE, the routes are increasing their metrics. Don't increase their metric if we redistribute with E two routes. So in this example, we'll use E to redistribution because it tells us that all rods -- sorry, these rods -- should not increase their metrics. All right. Secondly, after configuring first step we are goingto take a look which router is Dearand which is BDR for area zero. Okay? Then we'll define router one deer in area zero, and routers two and three will be defined without regard to a BDR or a BDR. Okay? After this configuration, what kind of neighborship was established between routers one, two, and three? Okay, we'll check. Then we are going to configure summarization on AB and ASPRS. We just have an ASPR. I'm sorry. And for ABS, which is actually two. Okay, let's start with the first guy. I'm going to cover your OSPF for the network above, and instead, SPF, which makes reservations, should be used. All right, let's go. All right, let's start with one. I'm going to check the interfaces by using the Show IP interface brief command first. And I'm going to advertise this network by using a router ID of one on OSPF, and I'll also redistribute these static routes into the OSPF domain. Okay, coffee, or rather an OSPF one. The first thing I do when I'm making an SPF configuration should be to define the router ID. Please keep in mind that if you define the routerID leader, you need to clear the OSPF process. So the first thing you should always do is to define the router ID. All right, router ID 1111, network 255 in area zero, and I'm going to redistribute the static subnets with an ametric of 200 and metric type of be e two.All right, the metrics always will beconstantly 200 because I'm using E two. All right, Roger. One is okay. Let's take a look at this guy Rodger SPLM. I'm going to define network statements. blank star reservoir. All right, that seems cool. Show IP interface in brief Please keep in mind that first type "show IP interface brief," then "advertise the interfaces." All right, comfy router ID: first drive-in area 00:20 in area 20. Okay, let's go. Show IP interface in brief We have loop packs in here as well, so we need to advertise them too. Okay, router SPF one. network from 200 to 55. Area 20, network town 255. All right, let's go to this guy. Confirm ID 100 and in-area time. Are the loopbacks the same, or am I confusing you? Oh no. Okay, in weather 1010, weather four is different. Okay, so no problem. We did something wrong. No. network will be in area zero. They are going to block two. Okay, now they belong to Ten. Alright, I finished the configurations, so I'm going to take a quick look to see if they're looking correct or not. Sharon. Okay, I'm not going to check one by one. I'm going to check if there's a problem in the configuration. Okay, one is aspiration and the other is redistribution. Okay, these routes are not increasing their metrics. All right, I used E, and they have a beginning metric of 200. All right, I configured then all routers shouldhave a router ID similar to their names. All right, the first step is accomplished in the second after configuring the first step, which is Dr and BDR in area zero. Let's go. Show IPOs. PF neighbour is the command that I used to check for deer and BDRs in an area. All right, router number two is the BDR in here. So who is there? I couldn't see any doctors in here. As you can see, OSPF neighbour and Dear are rather similar. All right, Dr is one for area zeroand PDR is rather two for area zero. Second step is okay, two then define rather one. SDR in area zero. It's already done. This guy is already Dr now soI don't need to configure anything else. Then define rather two and rather three ones. This guy is a bidder right now, so it won't be a PDR. So, this guy also won't be a deer or BDR. So we're not going to configure diskit to be a DEAR or BDR. I need to decrease the OSPF priority on the interfaces. Then we're all the magic happen. Rather two is speedier right now and let's see. Okay, both of these guys, two and three, are Dr. Other right now, which means it is not a Dr. or PDR. Okay, but not OSFP. can see in here. Rother one is still there. Okay, we accomplished this step two. But we are going to check after the configuration whichkind of a neighbour ship established between route two hasa full neighborship, 23 has a two way neighborship. The routers within an area make up a full membership with a designated router. And there are other routers that provide two-way adjacency with themselves. This is what this guy is asking us. All right, the first step configure summarization onABR rather on router two and rather three. I'm going to configure a summarization method that summarises the loop IP addresses while I'm sending to another one, and I'm going to take a look to show up your route. And I'm receiving all these prefixes. As you can see, I'm getting these from Roger Four and Five. All right, what I'm going to do is summarise these guys so that one will have a smaller routing table. Okay, let's go to router two first. I'm in router two, and I'm going to summarize. Okay, this IPN submission covers all networks and all loopbacks of the other guys. Okay, in router tree area 20 for this time range. Let's go check out the other one again and see what I find there. What I'm expecting is that I don't want to see them separately. I just want to see summarised routes instead of disguised ones. And I'm receiving them right now—as you can see, just ten times is what I'm receiving.Okay, I configured summarization on AVR. Rather, the final step informs me that I should configure summarization on ASP or rather this time. I'm going to summarise this static route, and I'm going to check what's going on. I'm going to go to router one this time, router SPF one. And when I'm summarising by using the ASP, the comment is a summary address. Summary address. And that's it. That's the old thing. Okay, guys, I configured and did the summer session on ASP, or rather, too. And that's the whole thing. We came out of our lab session, and thanks for viewing.

5. LAB - Advanced OSPF Configuration

Lottoy. Welcome guys. We have six steps to complete, starting with configuring OSPF for the topology and redistributing the static routes on Rather 1. Where is Router One? This guy has external static routes, so we need to redistribute them into OSPF as Type E ones. Okay, so in the second OSPF, because you can't be established if there isn't an OSPF router, which means we are going to configure passive interfaces somewhere in the third router in area zero, which must be configured with Nd 5 rather than area 23, which must be configured with clear text authentication. and our key is going to be y is going Then routers in area 45 should not receive external routes out of the OSPF domain. What is domain.Routers in area 23 must not receivetype three, four and five LSAs. These routers must reach the external network via the default route, which costs route, whAnd last, all routers should ping each other. Okay, how are we going to accomplish these steps? Let's start with the first one. I'm going to configure OSPF for each other, and the first thing I'm going to do will be defining the router ID. Then I'm going to advertise the networks. Then I'll configure redistribution on routers 1 and 2 to provide connectivity. Okay, the redistribute route will be E one.I'm going to take care of that. All right, let's go with router two. Show IP interface breath. We have some networks; where does this guy belong? All right, 10/100 belongs to area zero, and the other guys belong to areas 2 and 3. All right, router SPF one, router ID array 00:10:10 255, let's go ahead again. The thing I'm going to configure is the router ID first, and then let's advertise the network. And please keep in mind that we need to configure one more thing for this guy, which is redistributing. Redistribute static subnets metric. The actual question does not mention metrics, but I will provide 50 and metric examples. They're going to be E ones. Okay, cool. Rather, six depicts an IP interface in this area. I'm feeling tired guys, please help me. I forgot the Rather ID statementon the previous router I think. and clear on the previAll right, network 45. It takes really long to configure all of these guys.We have some loopbacks in here. I'm going to also advertise these guys too. PF one zero twenty-three is a very wise number. And the network will belong to areas two and three. One two, display the IP address of the interface breath and the router SPFone seven seven, network the last router OSPF one. Router ID: eight. did I configure? Yes, show your IP address in your breath and network. Pretty cool. The first step must be finished, I think. Let's check what's going on in our network. We're looking at the topology. Configure your SP for the topology above. redistribute static graphs on the router first; type "E" one accomplished; then nothing. All right, this guy's finished. Let's go ahead with the second step. OSPF adjacency must not be established if there is no SPF router. Okay, it's telling me that if there is an OSPF router that has an interface connected to a router, configure a passive interface. There it is, saying "me there." Okay, to configure a passive interface, for example, we can configure it here. Let's take a look. Okay, I'll do something different for this situation, and I'll learn something else as well, but I'll just configure it on one. I don't want to lose time with the passive interface commands. I'm just going to choose one, and I'm going to configure the passive interface in a different style. Okay, let's go with maybe five. looks like a good choice. Okay, router SPF 1, and I'm configuring passing interface default to enable passive interface on all interfaces. Okay, as soon as I configure it, my OSP adjustance is down, as you can see, because I'm not sending hello packets from the fast Ethernet one, which has a configured IP. I'm just going to activate this guy in here by using the nopassive interface fast one command. Okay? You will do it on each router. You can check the configuration. This configuration can be done on each router. But I'm not going to lose time by doing this. I just wanted to show you how to configure it. Okay, then in the third step, it's saying that rather than in area zero, disc guys 1, 2, 6, and 4 must be configured with MD 5. All right, this array will be MD-five authenticated, and this area will be clear text. authenticated, clear text. All right, I need to again configure all these steps on four routers in area zero, but I'm just going to configure it for router one, perhaps. Okay, you'll make the same configuration for two, six, and four as well. You need to do it. Okay? And for Area 23, I'm going to configure three routers to show you how we can configure them so that the configuration is consistent with the other routers. So I don't want to lose time again, but I'm just going to show you how to configure it. Okay, let's start with MD-5 configuration on, for example, router 1. Router one, where you are in router one, has interface zero, which is the interface in area zero. I'm going to configure IPOs PF authentication, which has a type of message digest. Then I'm typing IPOs OSPF message digest key one, MD five, and the R key is going to be Cisco. All right, this is how we configure the MD5 authentication for the router in area zero. As I previously stated, you must configure the six in the same manner as the two and four. As you can see, the neighbours are down right now. Okay. Because we have a key, we are using authentication message digest authentication right now. Okay, let's go to this guy. Instead of showing IP, I'm going to configure clear text authentication in this guy. In brief, I'm using this interface for this area. This time, I'm only typing IPFauthentication to activate the clip text. Then I'm using IPO's authentication key. Pretty cool. And I accomplished the third step as well. Okay, accomplished. But I want to show you something PO's autheI'm going to make a quickconfiguration for the other guys too. For example, where is the neighbor's ship? Three and two should come back. Yes. Then I'm going to configure six, two, and 42. I said I didn't want to waste your time, but I wanted to show you something on the next step. So I'm going to configure it. I'm sorry. As a result, IPF authentication and message keymask 5 are used. All right, let's go to "show IP entry." So let's copy this guy and go to six fast messages digest and paste this. And lastly, we need to go to router two, I think on router 20. Now we're finished. Okay, let's go to the first step. It's saying that rather than area45, where are area 45? These guys should not receive the external routes out of the OSPF domain. And these are the routes that are being redistributed by a rather large one, right? I don't want to see this guy in this area. So if I don't want to see an external route in an area, I need to configure the area as "stop. Right? I'm going to configure a stop for zone 45 on routers four and five, four, SPF 1, and zone 45. As soon as I type it, my neighbour is down because top is a flag when we configure the adjacency in OSPF. Then let's go to router five, or rather, SPFone and area 45, which makes my neighborship full again with the other five. All right, I set this to stop. So I need to take a look at why I should IP route.Okay, as you can see, I'm receiving some routes from the inter areas.I'm receiving interior routes, and I'm also receiving a default route. Okay, this default route I'm receiving is because this area is a stop area. I'm not receiving any external routes right now. So what I'm configuring is actually "by stop" as a default route. I'm configuring a default route and I'm sending anything else other than this network to this IP address. As you know, that's the only single output point already.Okay, four is okay to use rather than area 23 this time. Where are you guys? All right, this is going to be because I don't want to receive type 3, type 4, and type 5 LSA. Okay, let's go to router two. And I'm going to configure the other three first. Actually, other three rather SPF one and areastub and on ABR, which is rather two. I need to configure area no summary this time, which makes this area a totally stub area on this router. I configure the stop-no-summary no summary.Please pay attention to the fact that I'm configuring stop on the router tree and I'm configuring stop non-summary on the AVR. All right, let's go and take a look. Show re the stoOkay, what I'm seeing from the brother tree's point of view is just a default route. I don't see any interior routes as well.I don't see any external routes. I don't see anything. What I'm seeing is just a single output point, which is this IP address. And that's it. We don't need to do anything more. and I configured this as the total stubby area. All right, then all rodders must paint together. Let's go and take the figure. Take a look at the figure. Are you seeing something different? I'm seeing what I'm seeing in here, which is that we need a virtual area configuration to configure a virtual area, and we need to make a virtual link between some brothers. So first, let's define the virtual area. I'm sorry, where do we need to define the virtual link? Okay, all areas should be directly connected to area zero, which is the backbone, but I can see that this area is not directly connected to the backbone area, as you can see that.So what I need to configure is just a virtual link between routers six and seven. All right, I'm going to configure a virtual link to reach router 8 via eight routes. Okay, let's go to router six, virtual link, and the router idea of the neighbor. so I need to configure it on this guy. Also, what's going on here is the configuration of the virtual link and pressing Enter. And I accomplished this step too. Now all my routers should ping each other because I have correctly configured the OSDF for my network. Okay, guys, that was a really cool session. I think that you learned a lot, and it takes almost a half hour to configure all of these steps, but there was a really cool session, as I told you. And please keep in mind that you should study and that you should also make your own apps. You should configure something like that, and you need to study on that one too. Okay, guys, this session has finished, and thanks for viewing.

6. 3_4 OSPFv3

In our next section, we're going to talk about OSPF version three. OSPF version three is the IP version six-compatible version of the OSPF routing protocol. And the basics of the protocol are the same as in IPV 4 and OSPF version 2. Let's see how we can configure OSPF version 3 to configure IP version 6 on IOSPF version 3. First we enable the IP version six by typing IPversion six router SPF one on the config mode. Then we just define a router ID in this config line. After entering the router's interface mode and typing IP versions, OSPF, and ProcessID area, and the area of the interface that belongs to, that's all there is to it. To verify OSP version three adjacent C, the command we are using is "show IP in IPV 4." As you know, show IP version six OSPF neighbors, and we can see the router ID, the state of the neighborship, the interface, and their time details as well. In OSPF version three, we have two new LSA types: type eight and type nine. Type-eight LSAs allow the router to send a Link local address to other routers on the Link. It also informs other routers on the same link about the IP version six preferences on the link. And a router can also spread multiple intraarea prefixes for each router or transit network. Type 9 LSA indicates whether it's a router LSA or a network LSA. And we have a new type configuration in OSPF version three. Two new OSPF version three configuration supports IPV fourand IP version six with a single OSPF threeprocess and it's valid after iOS 15 one threeS and later versions we have IP version fourand IP version six address families. As you can see, the new type of OSPF version three configuration enables the OSPF version three operation on the interface to be optionally enabled for IPV4 or IP version 6 address families. To activate them, here is the configuration. We just get into interface mode. Then what we type is OSP version three process number IPV four for IPV four configuration and IPV six for IPV six configuration, then area and area. And here is how we can see the OSPF version three LSTB: A router brings up a single OSPF version three database containing different LSA types. Some LSAs contain information about IP version 4, some about IP version 6, and some about both. To view it, enter the Show OSPFversion 3 database command, and then check the interareaprefix, for example, by entering the interior prefix command. So let's take a look at how we can check the OSPF version three IPV four route table. To monitor it, you can type "ShowIP route" and "OSPF version 3 just." And if you want to see the OSPF version three IP version six routing table, the thing you are going to type show IP version six route," and you can see just OSPF routes by typing "OSPF" at the end of the command. And to configure OSPF version three total stub area, what you're going to do is type the router SPF version three and the process number. Then you get into the address family that we want to configure. And in this example, that's IPV 6 unicast. Then what you're going to do is almost the same thing with OSPF version three. You type the area two stops, no summary for the AVR, and you type the area stop for the other router in the area to configure OSPF version three summarization. You're going to update OSP version three and the process number once more. The address family is obtained by typing addressfamily IP version six for this example in unicast. And the command is just a summary prefix. You type the summary prefix and the summarise perfect this time.
