Hello,

I have two internet connection from the same provider.
1st. is a 6mpb primary
2nd. is a hardline T-1 secondary
My question: How do i configure my cisco 2600 to switch over to the secondary line when the primary goes down. I do not want to run BGP.


Thanks

!Default route to primary link's router
ip route 0.0.0.0 0.0.0.0 1.1.1.1
!Default route to secondary link's router with higher AD
ip route 0.0.0.0 0.0.0.0 2.2.2.2 250

Now if you do "show ip route" you should only see the 1.1.1.1 route... If the 1.1.1.1's network went down, then 2.2.2.2 default route would be installed....

If you post more specifics, I can help you.

Here more info.

From router A
i have two routes 1st. 216.237.72.0/27 goes to my t-1 router with no AD....
2nd. route of 216.237.72.0/27 with an AD of 250 that goes to the a switch that is connected a router that provides the 6mbps
................................
From the T-1 router
I have one route that goes over the serial

From the switch
I have one route that goes over to the my router

From my router
I have two default route
0.0.0.0 0.0.0.0 10.0.1.1-----------over the 6mbps
0.0.0.0 0.0.0.0 10.0.10.1 250-------over the T-1

This does not work. It seem that the router A does not know how route to the backup route when the primary dies

Thanks

It could be the ISP doesn't have two routes to your network. I.E. if you have say a /24 or something behind both of these routers, make sure your ISP has two static or dynamic routes to that subnet.
