That's the problem everyone has with the NON-EXIST-MAP :) Usually the IP prefix used to address the ISP-1 infrastructure is the best bet. The "match as-path" statement in the NON-EXIST-MAP is irrelevant (unless I'm totally wrong about the match being made with the routes in the IP routing table :). Ivan

Which prefix should i trust from ISP-1 (Primary ISP) ? Is it necessary to use "match ip address" and "match as-path" statements together in the NON-EXIST route-map ?

The access list used in NON-EXIST-MAP is used on the IP routing table, not on the BGP table (that's why the AS path doesn't work either).
