I currently have three routers, we'll call them routers A, B, and C, where I'm routing EBGP to external providers, and where I have IBGP on each with belonging to the same peer group. Each of these three routers are c7500s.
Question: I'm bring up EBGP on another router. Will I need to route IBGP in the same peer group on this router? There are two intermediary routers between this new router where I'm turning up EBGP. So, the topology is:
Routers D, E, and F are all c7206s, with 128M ram.
I'll be bringing up up EBGP on router F.
I am not using route reflection.
Do I need to route IBGP on router F? Or can I just let the BGP on router F inject into the routing protocol (OSPF) ?
Thanks in advance.
