Cisco CCNP / BSCI Certification: Route Redistribution Along with the Seed Metric
In the main portion of the free of charge CCNP / BSCI tutorial, we looked at how leaving one particular simple word from our route redistribution configuration – “subnets” – resulted within an incomplete routing desk when redistributing routes from RIP to OSPF. (If you skipped that Component of the tutorial, check out my Web-site’s “Free of charge Tutorials” section.) These days, we’ll examine redistributing OSPF routes into RIP and recognize Yet another common redistribution error.
We're employing a a few-router network. R5 is running RIP, R1 is serving being a hub amongst R5 and R3 and is https://socialhattori.com/ also operating RIP and OSPF, and R3 is working OSPF.
To start this lab, we’ll include a few loopbacks to R3 and advertise them to R1 through OSPF.
R3(config)#int loopback33
R3(config-if)#ip address 33.3.three.three 255.255.255.255
R3(config-if)#int loopback34
R3(config-if)#ip handle 34.3.three.3 255.255.255.255
R3(config-if)#int loopback35
R3(config-if)#ip handle 35.3.3.three 255.255.255.255
R3(config-if)#router ospf one
R3(config-router)#network 33.3.3.3 0.0.0.0 spot one
R3(config-router)#community 34.three.three.three 0.0.0.0 space one
R3(config-router)#network 35.3.three.3 0.0.0.0 space 1
R1 sees all three of those routes in its routing desk.
R1#show ip route ospf
34.0.0.0/32 is subnetted, 1 subnets
O IA 34.three.three.3 [110/sixty five] by way of 172.twelve.123.3, 00:00:fifty five, Serial0
35.0.0.0/32 is subnetted, 1 subnets
O IA 35.three.3.3 [one hundred ten/sixty five] by means of 172.12.123.3, 00:00:forty five, Serial0
33.0.0.0/32 is subnetted, 1 subnets
O IA 33.3.three.3 [one hundred ten/sixty five] by using 172.12.123.3, 00:00:fifty five, Serial0
We’ll now redistribute these routes into RIP on R1. Bear in mind the “subnets” option we talked about in the main aspect of the tutorial? There isn't a this sort of alternative when redistributing OSPF routes into RIP, as IOS Help exhibits us.
