An easy way around this is to be consistent about your transit and peering arrangements across locations. If your anycast network has transit from a network in one location, get transit from them in your other locations, and let hot potato routing do its thing. For cases where this isn't practical, or where you want more control over who is sending traffic to a node, declare the node to be a "peering only" node and make sure your peers aren't leaking the anycast routes to their out of region upstreams.Or prepend (gasp!) like the Dickens for your "peering only" node to have transit, but be the route chosen after transit/connectivity to your "transit/peering ok" node fails.
Doesn't work. Local preference gets considered before AS path. -Steve
