Just as a first step. After you applied your filter did you issue a clear
ip bgp *?
Also, before you applied the filter were your neighbor sessions showing as
ESTABLISHED?

Hi all:
Here is the scenario:
EBGP IBGP EBGP IBGP
R1-----------------R2-------R3------------------R4---------R5
R1 = AS100 Advertises network 10.0.0.0
R2 and R3 = AS200 Advertises 30.0.0.0 and 50.0.0.0
R4 and R5 = AS300 advertises 20.0.0.0 and 40.0.0.0
If I apply a inbound filter-list on R4 as below,
start
!
neighbor <R3's address> filter-list 10 in
!
ip as-path access-list 10 permit .*
!
end
I loose are R2 and R3 originated routes but I still have R1 advertised
route.
I thought .* (dot star) was like DOS's *.*. Why am I not seeing
directly attached AS's routes.
I am using 11.2(12) on a 2500 on R4.
Thanks for your help in advance.
