Ask your AT&T rep to get you the AVPN routing guide. That have a whole list of functions that can be manipulated by changing community information you send with a route. It is very useful and you would never figure it all out by just messing with it. I would send it to you but I don't have access at the moment.

I see that they stamp several on the routes we originate (Community: 13979:2741 13979:2943 13979:5000 13979:6551) and curious if anyone had luck adding their own before I go start mucking around. Thanks!
