Can I redirect ip traffic from one router to another router?

[chloi]

Hi, I wanted to install 2 router in one site. But, all of them in one same VLAN. since only one default gateway can be set at the client machine, I want the primary router to decide what traffic to be redirect to the secondary router. e.g.: router1 serve only ftp traffic. Others traffic would be redirected to router2.

thanks.

Hi,

you can use policy routing for example to set the next-hop for some specific traffic (defined with access-lists). the following link shows a configuration example:

or search for:

ip policy route-map, route-map, set ip netx-hop

As Mark has pointed out Policy Based Routing would be one way to accomplish what you have described. And it would work as you describe.

But I wonder about your statement about having only one default gateway and I would suggest that you think about HSRP. With Hot Standby the client machine is configured with a default route address. That address is shared by both of the routers as a virtual address. The routers negotiate which one will be the lead and that is the one that traffic goes to. If the lead router fails the standby router takes over and all the traffic transparently is sent to it.
