Lab 25: OSPF Multiple Area Routing, Route Redistribution and Summarization ”Part IILab WalkthroughConfigure the Frame Relay switch and attach the four routers in a back-to-back manner to the Frame switch. Use V.35 cables or CSU/DSUs with crossover cables to connect the routers. Create the five LANs by the use of switches or hubs/MAUs, as illustrated in Figure 12-16. When the physical connections are complete, assign IP addresses to all LAN and WAN interfaces, as depicted in Figure 12-16. Configure three loopback addresses on the chameleon router with the addresses 10.1.16.0/24, 10.1.17.0/24, and 10.1.18.0/24. Be sure that you can ping each router's local LAN and WAN interface before continuing. You will use frame-relay interface-dlci commands on all of the point-to-point interfaces. Example 12-48 lists the Frame Relay configurations, to this point, on all routers involved.

To configure the WAN network between python and the boa, one end will need to be configured for clocking, or DCE. Example 12-49 lists the serial configuration of the boa router, which is the DCE side of the link. This is not necessary if you are using CSU/DSUs with crossover cables. Example 12-49 Serial Configuration of the Router boa! interface Serial1 ip address 10.1.80.2 255.255.255.0 clockrate 56000 After the LAN and WAN interfaces have been configured and basic IP connectivity has been established, begin to configure OSPF and IGRP. First, you will configure OSPF, and then you will integrate it with IGRP. Recalling the detailed process to configure OSPF, you have the following:
Step 1 involves area design. In this model, the Frame Relay point-to-point networks are in OSPF Area 0. The LAN interface of the gecko router is in OSPF Area 10, while the LAN interfaces of the tree_frog and python routers are in OSPF Area 20. The serial interface of the python router and all the interfaces of the boa router are in OSPF Area 75. As you probably can tell at this point, you will need a virtual link to connect Area 75 to the rest of the OSPF network. Step 2 involves setting RIDs on the routers that have Cisco IOS Software prior to Release 12.0. To accomplish this, you will use loopback interfaces on those routers. Figure 12-17 shows the diagram with the router IDs that you have assigned and the virtual link marked . Figure 12-17. HIN with RIDs Assigned Again, Step 3 is where the real configuration begins. On all the routers except chameleon, you will enable OSPF in AS 2001 with the command router ospf 2001. On routers that have Cisco IOS Software Release 12.0, use the router command router-id ip_address to assign the static RIDs to the routers. Step 4 involves configuring which interfaces will participate in OSPF routing and the areas in which they will reside. On the hin_hq router, the E0 interface will be in Area 0, along with the s0.1 and s0.2 point-to-point interfaces. Example 12-50 lists the OSPF configuration, to this point, of the router hin_hq. Example 12-50 Preliminary OSPF Configuration of hin_hqrouter ospf 2001 router-id 192.168.200.5 redistribute igrp 2001 subnets tag 5 network 10.1.5.1 0.0.0.0 area 0 network 10.1.128.1 0.0.0.0 area 0 network 10.1.129.1 0.0.0.0 area 0 default-metric 64 ! The network statements in the previous example could be simplified with one command ” network 10.1.0.0 0.0.255.255 area 0. In production networks, it pays to be specific on the mask. As changes occur in the network, new interfaces in different areas might be added. If the wildcard mask is too general, OSPF will have to be interrupted while new, more specific network statements are configured. The LAN interface of the gecko router resides in OSPF Area 10, while its serial interface resides in OSPF Area 0. The tree_frog routers LAN interface resides in OSPF Area 20, while its serial interface also resides in OSPF Area 0. Example 12-51 presents the preliminary OSPF configurations for the gecko and tree_frog routers. Example 12-51 Preliminary OSPF Configurations of the gecko and tree_frog Routershostname gecko ! router ospf 2001 router-id 192.168.200.6 network 10.1.6.1 0.0.0.0 area 10 network 10.1.128.2 0.0.0.0 area 0 ! ________________________________________________________________ hostname tree_frog ! router ospf 2001 network 10.1.1.1 0.0.0.0 area 20 network 10.1.129.2 0.0.0.0 area 0 ! NOTE The tree_frog router does not show a router ID because it is using a loopback interface for its RID. The tree_frog router is running a Cisco IOS Software Release prior to 12.0. The python router will have one interface in Area 20 and one in Area 75, while the boa router will have both interfaces in Area 75. Example 12-52 lists the OSPF configuration of these routers. Example 12-52 Preliminary OSPF Configuration of the python and boa Routershostname python ! router ospf 2001 network 10.1.80.1 0.0.0.0 area 75 network 10.1.1.2 0.0.0.0 area 20 ! ____________________________________________________________________ hostname boa ! router ospf 2001 network 10.1.0.0 0.0.255.255 area 75 ! Step 5 requires you to configure the additional neighbor support. In this model, adjacencies automatically form over the Frame Relay point-to-point networks. No additional neighbor configuration support is needed. At this point, OSPF is operational, except for Area 75, and you have IP connectivity to every router in the network. To verify this, you can examine the neighbors and route table, as well as perform standard ping s tests. Example 12-53 lists the output of the show ip ospf neighbor commands on the hin_hq, gecko, tree_frog, and python routers. Example 12-53 Verifying OSPF Neighborshin_hq# show ip ospf neighbor Neighbor ID Pri State Dead Time Address Interface 192.168.200.6 1 FULL/ - 00:00:35 10.1.128.2 Serial0.1 192.168.200.1 1 FULL/ - 00:00:32 10.1.129.2 Serial0.2 hin_hq# __________________________________________________________________________________ tree_frog# show ip ospf neighbor Neighbor ID Pri State Dead Time Address Interface 192.168.200.8 1 FULL/DR 00:00:35 10.1.1.2 Ethernet2 192.168.200.5 1 FULL/ - 00:00:34 10.1.129.1 Serial0.1 tree_frog# __________________________________________________________________________________ phython# show ip ospf neighbor Neighbor ID Pri State Dead Time Address Interface 192.168.200.1 1 FULL/BDR 00:00:39 10.1.1.1 Ethernet0 192.168.200.7 1 FULL/ - 00:00:35 10.1.80.2 Serial0 python# Step 6 requires you to configure OSPF special areas, such as stub areas ”or, in this case, virtual links. As mentioned previously, you will need a virtual link to connect Area 75 to the rest of the OSPF domain. To configure a virtual link, you need to locate the two routers that will serve as your endpoints for the virtual links. In this model, Area 20 will be your transit area; therefore, your virtual links need to be defined on the routers tree_frog and python. The syntax on the tree_frog router will be area 20 virtual-link 192.168.200.8, which is the RID of the python router. The python router, in turn , points to the RID of the tree_frog router. The syntax on the python router will be area 20 virtual-link 192.168.200.1. Static router IDs are vital to the operation of OSPF virtual circuits. If you have trouble bringing up the virtual link and have verified that there are no configuration errors, try reloading the routers. A common problem with virtual links is RIDs, and this will reassign them in routers running Cisco IOS Software prior to Release 12.0. To view whether the virtual link is working, use the show ip ospf virtual-link command. The routes from the boa router also should start appearing throughout the OSPF domain. Example 12-54 lists the output of the show ip ospf virtual-link command on the tree_frog router. Example 12-54 Verifying the Virtual Link tree_frog# show ip ospf virtual-links Virtual Link OSPF_VL0 to router 192.168.200.8 is up Run as demand circuit DoNotAge LSA allowed.

By viewing the route table on the boa router, you can see that you have routes to every destination in the network, as shown in Example 12-55. Example 12-55 Verifying the OSPF Domain boa# show ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default U - per-user static route, o - ODR Gateway of last resort is not set 10.0.0.0/8 is variably subnetted, 8 subnets, 4 masks O IA 10.1.1.0/27 [110/74] via 10.1.80.1, 00:28:02, Serial1 O IA 10.1.6.0/28 [110/212] via 10.1.80.1, 00:28:02, Serial1 O IA 10.1.5.0/24 [110/148] via 10.1.80.1, 00:28:02, Serial1 C 10.1.70.0/24 is directly connected, Ethernet0 C 10.1.80.0/24 is directly connected, Serial1 O IA 10.1.129.0/24 [110/138] via 10.1.80.1, 00:28:02, Serial1 O IA 10.1.128.0/30 [110/266] via 10.1.80.1, 00:28:02, Serial1 O IA 10.1.128.0/24 [110/202] via 10.1.80.1, 00:28:02, Serial1 C 192.168.200.0/24 is directly connected, Loopback0 boa# To integrate the IGRP domain, configure IGRP on the chameleon and hin_hq routers. Example 12-56 lists the IGRP configuration on the hin_hq router. Be sure to use the passive-interface command to prevent unnecessary broadcast from the Ethernet and other serial interfaces. The IGRP configuration on hin_hq and chameleon will be identical. Example 12-56 Configuring IGRP on hin_hq! router igrp 2001 passive-interface Ethernet0 passive-interface Serial0.1 passive-interface Serial0.2 network 10.0.0.0 ! Next, you need to configure redistribution between IGRP and OSPF. There is only one redistribution point in the network, so you do not have to worry about route feedback or redistribution loops . Example 12-57 lists the configuration of the hin_hq router, highlighting the redistribution commands. In this example, you use an OSPF default metric of 64 because it is the cost of a T1 interface. You also use the subnet keyword to redistribute multiple subnets into OSPF. Example 12-57 Redistribution on the hin_hq Router! router ospf 2001 router-id 192.168.200.5 redistribute igrp 2001 subnets tag 5 After redistribution is enabled, if you viewed the route table on the chameleon router, you would find the results in Example 12-58. Example 12-58 Route Table of the chameleon Router chameleon# show ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area * - candidate default, U - per-user static route, o - ODR P - periodic downloaded static route Gateway of last resort is not set 10.0.0.0/24 is subnetted, 10 subnets C 10.1.3.0 is directly connected, TokenRing0 I 10.1.5.0 [100/8576] via 10.1.130.1, 00:00:00, Serial0.1 C 10.1.18.0 is directly connected, Loopback22 C 10.1.17.0 is directly connected, Loopback21 C 10.1.16.0 is directly connected, Loopback20 I 10.1.70.0 [100/8486] via 10.1.130.1, 00:00:00, Serial0.1 I 10.1.80.0 [100/8486] via 10.1.130.1, 00:00:00, Serial0.1 C 10.1.130.0 is directly connected, Serial0.1 I 10.1.129.0 [100/10476] via 10.1.130.1, 00:00:00, Serial0.1 I 10.1.128.0 [100/10476] via 10.1.130.1, 00:00:00, Serial0.1 chameleon# At first glance, it might appear that the route table is complete; however, upon closer examination, two routes are missing: 10.1.6.0/28 and 10.1.1.0/27. This is because IGRP can receive only routes that are on the same bit boundary as the interface receiving the routes. For the chameleon router to receive all the OSPF routes, they must be summarized on a 24-bit boundary that matches the bit boundary on its s0.1 interface. To summarize Area 20 and Area 10, use the router command area x range statements. The area range statement for the gecko router will be area 10 range 10.1.6.0 255.255.255.0, and the area range statement on the tree_frog router will be area 20 range 10.1.1.0 255.255.255.0. After adding the area range statements, the route table on the chameleon router now has all the routes to the OSPF domain, as verified by Example 12-59.

To summarize networks from another AS, use the OSPF command summary-address command. The aggregate address is 10.1.16.0 with a 255.255.252.0 mask.

To perform this, you need to change the ip ospf hello-interval on the E2 interface of the tree_frog router. If you change the timer on just one interface, the neighbor soon will drop and routing will be compromised. Whenever changing timers in OSPF, be sure to change the timers on all routers on the same IP network. In this model, you have to change the timer on the tree_frog router and also on the python router. Example 12-64 demonstrates the timer configuration on the tree_frog router. Example 12-64 Changing the OSPF Hello Timer on an Interfacetree_frog(config)# int e2 tree_frog(config-if)# ip ospf hello-interval 30 tree_frog(config-if)# To verify the timer change, check the status of the OSPF neighbors and perform the show ip ospf interface command on the interface.
