Hi there.
I'm looking for a Cisco doc or a quick guide to *best practice* for the following scenario: Provider A gets 5 upstream BGP feeds via two core routers. Provider B wants to purchase transit from Provider A but does not want to send/receive any traffic via one of Provider A's upstreams (Provider X in this case). Provider A also uses BGP communities to mark their downstream customers, their upstream connections etc. Obviously Provider A can simply not announce Provider B to Provider X solving this issue in one direction. but what about traffic coming into Provider A from Provider B that prefers Provider X outbound? I'm thinking that you could use route-maps on Provider A (which would already be in place anyways most likely) and local-pref Provider X's routes specific to Provider B's community? If this is the best practice, anyone have a config snippet they could share or is there is a better way? Thanks in advance, hopefully I'm explaining this well.
