We have a remote site with a T1 connection and a backup DSL line. On the DSL line, I would like to place an ASA 5505 with an "always-on" LAN-to-LAN tunnel back to our network. Of course, this would be so that if the T1 circuit failed, it would failover to the VPN tunnel over the DSL line. My question: Since the VPN Concentrator at the main site does not support EIGRP (used across the LAN/WAN), how do I configure routing at the main site to allow for this "failover"?
I have this problem too.
