When using a route-map, set next-hop. What happens if the next hop goes down or the link to the next hop goes down? Will the packet be dropped out of the policy and be routed normally, or will it still be sent to a non existent next-hop?
You do have the option of specifying two next hops (actually u can specify more that 2...i m not sure abt upper limit). In case the first next-hop specified fails...the packet is routed to second next-hop and so on.
If the interface associated with the first next hop specified with the "set ip next-hop" command is down, the optionally specified second or third IP addresses are tried in turn. If the link is down but there are no other set statements, packets are routed normally (i.e. the router uses policy routing first and then the routing table).
route-map traffic_source permit 10
match ip address 101
set ip next-hop 172.16.x.x 172.32.x.x
If the next hop goes down but the link is still up, the router will continually ARP for that downed router (i.e. you are black holed).
