We have a site which wants to connect back to our main office from an ASA running v7.2 via two different IPSec tunnels - one on the ASA's outside interface and one on its dmz. They want to set it up so that if the tunnel on the outside interface goes down, traffic will automatically reroute through the tunnel on the dmz. The equipment on the other end (the main office) is a Pix 525 running v7.2.
One of my coworkers said this could be done using dead-peer detection, but had no details on how to set it up. Can anyone point me to a document that shows how to configure this? I have so far been unable to find one on cisco.com.
