I'm trying to prevent a single host address from being injected into my providers MPLS network and even with the distribute-list it stills show up in the AS. Thanks..
router bgp 200
network 10.2.20.0 mask 255.255.255.0
neighbor 18.104.22.168 remote-as 65000
neighbor 22.214.171.124 route-map SETMED out
distribute-list 10 out
-even tried neighbor 126.96.36.199 distribute-list "" out
access-list 10 deny host 188.8.131.52
access-list 10 permit any
clear ip bpg *
clear ip route
int loopback 1
ip address 184.108.40.206 255.255.255.255
Just tested this with dynamips and it works fine for me, so as long as you have an exact matching route ie. 220.127.116.11 then it should work fine.
