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.
