Telnet to the backbone (192.10.1.254) and verify its routing table. Most
probably it doesn't have a route back to R4.

Which IP address are you pinging from on R4. The backbone router does not
know any of R4 ip addresses right ? Are you advertising any ?

Subject: bgp woes....synchronization problem<??>
i've got 2 router, r4 and r5 that are in the same as <200>. r5 connects
to
a backbone router at 192.10.1.254 in as 254 and is learning additional
prefixes from there.
the problem i'm having is that i can ping 222.22.2.1 from r5 but not from
r4, even though i have the network in stalled in the bgp table. i've tried
various methods to remedy this <route-reflector, synchronization, next-hop
self>, but i can't seem to make it work <getting very frustrated here.
i've included the configs for r4 and r5 along w/ the bgp tables. any
ideas
as to why i can't reach 222.22.2.1` would be MOST helpful!!!!!
