i did not have neighbor statements for router C in router B and in router B
for router C....that fixed it but why didnt router B pass the loc pref up
since it is in the same AS and has a neighbor statement in it.

Subject: Local Preference Problem
here is my topology (same topology as page 559 of the gold
saterlee/hutnik
book). router A (loopback 1.0.0.0) is in AS100 ebpg peering with router
B
and router C. both router B and C are in AS200. router B and C both have
a
link to router D which is also in AS200. im using ospf as my igp in
AS200. D
can reach A fine by bgp. ive configured router C to increase the local
preference to 200 of inbound routes from router A (about network
1.0.0.0).
when i do a sh ip bgp on router D the local preference is 200 and is
going
through router C to get to 1.0.0.0 which is what i wanted. however, i
cannot
get D to pass the local preference up to B that is in the same AS200. i
have
cleared ip bgp * on all AS200 routers. its my understanding that local
preference is passed within AS200(not externally) but I cant get router
B
the local preference info from D. am i missing something? thanks team.
