I'm sure this is possible but am unsure of what precisely i need to setup, maybe just RIP or EIGRP or ??? Basically I have 2 sites normally the WAN connection is a P2P T-1, both sites have their own internet and PIXs (506e so 6.x code) I want to setup on our routers that if the T-1 goes down route WAN traffic via VPN tunnels on the Pixs. How do i go about this? How would i setup the routing and how do i have the routers at each end know that the P2P is down use vpn and vice -versa the P2P is backup go back to using it.
Thanks for any help!
