How would i implement backup DR PVC's on frame-relay. I have a frame-relay network and my provider has assigned us backup PVC's. Our main office hosts the T1 host connection. My backup site is 1hr 30mins from the main office. Its out in the sticks and no access to DSL. Our plan is to host both our backup frame connection and back internet connection on the same physical circuit that currently exists at this site. Its a Full T1. It will be divided into 512k circuits. Dont ask why. Boss will not spring for the extra money. Having to make do with what i have. Something is better than nothing. My question really is how do i configure the remote sites to fail over to the backup PVC.

I would guess i would have to use a whole new IP subnet for the backup PVC's as well as use BGP or some type of routing protocol. Right now i use EIGRP.
Any sample confs or help would be appreciated.
Thanks
