Hello all!

I have a 7513 that has a single FastE circuit and of course a single default route for traffic. I am adding another FastE circuit from another provider and they have provided the /30 WAN and a /24 for LAN.

What I am trying to do seems pretty simple but for some reason it is just eluding me.

What I want to do is route out the /24 IP space the 2nd provider has given me out their interface.


I have the subnet routing out the default connection.

I need to route the new LAN out the /30 interface

Right now the traffic on the LAN side routes out through the firewall and once it hits the router it is being sent out the default GW even when I add a route like..

ip route

How would I do this?

PBR (Policy Based Routing)

access-list 101 permit ip any

route-map PNAT permit 10

match ip address 101

set ip next-hop

where 105 is the ISP address. If 105 is the ip address on your interface then it will be 106 which will be the ISP interface.

then on the LAN interface that connects to

int fa0/1

ip policy route-map PNAT

Let me complicate things :) Jon's response is precise and exact to your requirement.. but do you need service provider redundancy :) automatic fallbacks and stuffs like that ??
