Just trying to figure out something that I'm seeing in BGP, and determine
whether its normal behavior or not.
Suppose I have routers BB1----R1 --------R2-----R3----BB2
|
R4
R1, R2, R3, R4 are all in the same AS, BB1 and BB2 are in the same AS. I
have applied a local preference specifying all routes learned from the
external AS are preferred through R3 with a value of 200, routes learned
from R1 have a local pref for the external AS specified to 150. After
applying the corresponding access list to both R1 and R3, when I perform a
show IP BGP on R3 I no longer see routes for that are advertised by BB1
through R1. Is this normal behavior ???
Thank you.
Peter.
