No, the 204 netowrk is not in R3's bgp table. No routes are being advertised b
y R2 to R3. Therfore synchronization is not my issue. My issue is TCP connectiv
ity between R1 and R3. Once TCP is established the peer comes active. Simply ad
ding a static route on R3 solves the problem. My real question is why does R2 t
ell R1 about 165 network via BGP but R2 does not tell R3 about 204 network via
bgp. Neigbor sessions are active on both sides. I wouldn't suspect synchronizat
ion to be an issue unless I saw the route in the BGP table. In this case it is
not.
Thanks.

You need to have synchronization disabled to have IBGP routes populate the
routing table (despite the fact that they are in the BGP table).

Subject: IBGP HELP??
> I have AS 3127 with 3 routers. R1 is connected to R2 via Token ring. R2 is
connected to R3 via Ethernet. R1 and R3 do not have a direct connection.
They are attempting to peer through R2. R1 and R2 neighbor states are
active. R2 and R3 neighbor state is active. R1 and R3 neighbor state will
NOT come up. The network on link between R1 and R2 is 204.156.20.0/30 and
network between R2 and R3 is 165.40.22.0/23. From R1 I CANNOT ping R3. R1
has learned a route from BGP to R3. Looking on R3 it has not learned a route
to R1 (From R2). This is obviously why I cannot ping from R1 to R3 and this
is also why the BGP peer won't come up. Simply adding a static route on R3
pointing to R1 solves the problem and my BGP peers comes up. My question is
why does R2 tell R1 about the 165 network but R2 does not tell R3 about the
204 network? Why do I have to add a static to R3? Please help!!
