[c-nsp] BGP conditional advertisemet - NON-EXIST route map'saccess-list problem

[Burak Dikici]

Hi Ivan ,

 Ok than , what should i use for  NON-EXIST route-map's access-list ? 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 ?
