i am not sure about policy routing.
interface serial 0
ip policy route-map demo
route-map demo permit 10
match ip address 4
set interface serial 2 serial 3
access-list 4 permit 10.3.3.2
so if the packet is sourced from 10.3.3.2,it will be routed out interface serial 2 and serial 3 .but if there is no route for the packet's destination network in the routing table,should the packet still be routed out interface serial 2 and serial 3?
And if there are two routes for the destination network,how can they choose the route?Does these two interface routed in a load balance fashion?
