I think that's what you're looking for...

Subject: [c-nsp] BGP Distribute List

I have a distribute list setup to reference a prefix list in a bgp
configuration. However the outbound filtering is not working and I have
reset bgp connection with soft outbound reset.

Here is the config.

Any ideas why this is not working?

router bgp 100
 no synchronization
 bgp log-neighbor-changes
 network x.x.230.160 mask 255.255.255.252
 network 172.x.36.0 mask 255.255.254.0
 network 172.x.253.152 mask 255.255.255.252
 network 172.x.253.156 mask 255.255.255.252
 network 172.x.255.0 mask 255.255.255.0
 neighbor x.x.230.161 remote-as 65000
 neighbor x.x.230.161 weight 500
 neighbor x.x.230.161 distribute-list routeout out
 neighbor 172.x.255.252 remote-as 65535
 neighbor 172.x.255.252 distribute-list routeout out
 no auto-summary

I have reset the BGP connections in the outbound with soft reset but
still no luck. The router is receiving all routes from neighbors and
relaying them to the other EBGP router.  I am not worried about inbound
received routes, just outbound filtering based on a specific prefix
list.

Any ideas?
