Cisco CCNP / BSCI Certification: Route Redistribution And The Seed Metric
In the first part of this free CCNP / BSCI tutorial, we looked at how leaving one simple word out of our route redistribution configuration – “subnets” – resulted in an incomplete routing table when redistributing routes from RIP to OSPF. (If you missed that part of the tutorial, visit my website’s “Free Tutorials” section.) Today, we’ll look at redistributing OSPF routes into RIP and identify another common redistribution error.
We are using a three-router network. R5 is running RIP, R1 is serving as a hub between R5 and R3 and is running RIP and OSPF, and R3 is running OSPF.
To begin this lab, we’ll add three loopbacks to R3 and advertise them to R1 via OSPF.
R3(config)#int loopback33
R3(config-if)#ip address 33.3.3.3 255.255.255.255
R3(config-if)#int loopback34
R3(config-if)#ip address 34.3.3.3 255.255.255.255
R3(config-if)#int loopback35
R3(config-if)#ip address 35.3.3.3 255.255.255.255
R3(config-if)#router ospf 1
R3(config-router)#network 33.3.3.3 0.0.0.0 area...
