I have been working on BGP and I came across a problem. If I have 4 routers
setup in series R1 - R2 - R3 - R4 with R1, R3 and R4 as IBGP full mesh. When
I add in EBGP connections on R1 and R4 I can see the BGP routes on R3 as soon
as I do a no sync. R1 and R4 with next hop self and OSPF is running
internally. R1 and R4 are connected to another router via EBGP. Now to the
problem, If I try to ping from R3 to an external ip address that has been
learned via R1 the packet dies at R2 because R2 does not have the external ip
address in its table. I thought about adding a tunnel interface to R1 and R3,
but I am not sure if I have missed something.
Any thoughts?
