How do I apply a static route to a specific interface?

I have a default route 0.0.0.0 but I'd like some packets that come in on certain interfaces to have a different default route.

If you only wanted 192.168.1.0/24 to use the specific default route on a particular interface, something like this should work.

interface FastEth...

ip policy route-map mymap

access-list 10 permit ip 192.168.1.0 0.0.0.255

route-map mymap permit 20

match ip address 10

set ip default next-hop

Wow, this seems to be a popular answer.

Hi

You need to use Policy Based Routing for this. Attached is a white paper explaining how PBR works and what it can do. After reading this serach on Cisco site for your IOS version configuration docs and PBR will be in there.

Roland,

You can use PBR and match the intresteing traffic using an ACL to have it source routed to a different next hop IP. This way your specific incmoing traffic an interface will be policy routed to a different next hop router and the other traffic which doesnot match the PBR will follow the normal defualt route.

HTH,Please rate if it does.
