Question : Problem: Back-up a frame relay line with dsl

Hi all,

we have an office that is linked to corporate through frame relay. At that office we also have a dsl line linked  to corporate by vpn. We need that when the frame is down all the traffic to be automatically redirected through the other line. How can we accomplish this in an automatic way?

Thanks.

Do you have a cisco router at each site? If yes, then make this router's local IP the default gateway for the LAN, and put two default routes on it. One to the local sonicwall, one with higher metric to the WAN.
This way, if the WAN link drops, the specific route to corporate drops and all traffic goes through the VPN.

Example:
ip route 0.0.0.0 0.0.0.0 192.168.77.1 < = local sonicwall
ip route 0.0.0.0 0.0.0.0 10.100.200.2 200  <= WAN link backup default (optional) with metric of 200
ip route 10.0.0.0 255.0.0.0 10.100.200.2   <== corp network

Done.
