I've done this in the past as a work-around for insufficient BGP community support. Just prepending the AS I wanted to ignore the paths. But, if the problem is an anycast CDN choosing a sub-optimal path to reach you, you might try reaching out to them. They're probably just as, if not more interested, in getting their traffic to you as efficiently as possible. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route | therefore you are _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
