RIP Next Generation
Offset List - Is used to influence the RIP metric by adding additional hop to the paths.
#show ip route rip
...
11.0.0.0/24 is subnetted, 1 subnets
R 11.11.11.0 [120/1] via 192.168.12.1, 00:00:17, FastEthernet0/0
access-list 1 permit 1.1.1.0 0.0.0.255
offset-list 2 in 10
#show ip route rip
...
11.0.0.0/24 is subnetted, 1 subnets
R 11.11.11.0 [120/11] via 192.168.12.1, 00:00:26, FastEthernet0/0
When we redistribute something into RIP, we have to use a seed metric. You can choose if you want to set a metric yourself or if you want to use the transparent option. If you choose this then the router will use the value in the BGP MED as the metric. Let’s try this:
PE2(config)#router rip
PE2(config-router)#address-family ipv4 vrf CUSTOMER
PE2(config-router-af)#redistribute bgp 234 metric transparent
