Burak,
ip as-path access-list 1 permit ^200 !!! (ISP-1 AS number) !!!access-list 65 permit any !!! (permit any packet from ISP-2) !!! route-map NON-EXIST permit 10 !!! (this matches any route from AS200) !!! match ip address 65 match as-path 1
you can match only on ACL and prefix-list int the *-EXIST-MAPs. Also you dont match packets rather prefixes. So choose a ISP-1 prefix (some infrastructure IPs or so) and match in prefix-list/route-map. Then if it is gone, start advertisiing to routes in ADVERTISE Best Regards, -mat -- pgp-key 0x1C655CAB
