   The route map in the "advertise-map" part of the command tells the
   router which routes to advertise when others are down. The route map
   in the "non-exist-map" section tells the router which network has to
   be down in order to advertise the network in the advertise-map.
   
   
   
   neighbor 10.1.1.1 advertise-map BACKUP non-exist-map MAIN
   
   
   
   router bgp 3
   
    neighbor 10.1.1.1 remote-as 6
   
    neighbor 10.1.1.1 advertise-map BACKUP non-exist-map MAIN
   
   
   
   route-map BACKUP permit 10
   
    match ip address 1
   
   
   
   route-map MAIN permit 10
   
    match ip address 2
   
   
   
   access-list 1 permit 192.168.2.0
   
   access-list 2 permit 192.168.11.0
   
   
   
   In this scenario, the router will advertise 192.168.11.0. If this
   route goes down, it will advertise 192.168.2.0.
