to forward a certain destination address over another
next hop use the following:
access-list 101 permit ip any host 192.168.1.2
route-map layer3 permit 10
match ip address 101
set ip next-hop 192.168.1.3
and in global config mode you need:
ip local policy route-map NAME
This forwards a packet to next hop 1.3 if someone tries
to reach 1.2
