Hey Marc, You can prepend on incoming or outgoing but only for eBGP neighbors, I don't think this will work with iBGP.

R8 has an iBGP BB1 peer that is advertising some routes. I need to make sure that other AS's prefer BB1 for these routes and I can only make changes on R8. So I thought I could just place a route-map on the iBGP peer that does AS-Path prepend but it doesn't seem to work. Here is my config: router bgp 218 no synchronization bgp log-neighbor-changes network 193.44.0.8 mask 255.255.255.255 neighbor 193.44.0.21 remote-as 218 neighbor 193.44.0.21 update-source Loopback0 neighbor 193.44.0.21 send-community neighbor 193.44.0.21 route-map asprepend in neighbor 193.44.78.7 remote-as 17 neighbor 193.44.78.7 password ipexpert neighbor 193.44.78.7 send-community route-map asprepend permit 10 set as-path prepend 218 218 218 I realize that I can probably do a bit more work and match the actual routes. Does AS-Path prepend only work on outbound routes? _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
