Hi
I am trying to do filtering.
I am using filter-list. --- NOT working

      AS-65000 AS-123 AS-456
----------[ R1 ] ------------ [ R2 ] ------------- [ R3 ]

In the above senario, on R2, I dont want to send routes
that start from AS65000 to AS 456.
I am using a filterlist with neighbor command and its NOT working

R2#sh run | in ip as-path
ip as-path access-list 1 deny _65000$
ip as-path access-list 1 permit .*

R2#sh run | be bgp
router bgp 123
 no synchronization
 bgp log-neighbor-changes
 network 4.4.4.44 mask 255.255.255.255
 aggregate-address 209.112.0.0 255.255.0.0 summary-only
 neighbor 140.100.45.2 remote-as 1111
 neighbor 140.100.45.2 next-hop-self
 neighbor 140.100.47.7 remote-as 456 <------------------- for R3
 neighbor 140.100.47.7 password ccie <------------------- for R3
 neighbor 140.100.47.7 filter-list 1
out <------------------- for R3

After this I see all the routes that start on R1 in R3.
Not sure what I am doing wrong.

Thanks
Kal
