VPN tunnels not reconnecting after Internet failure

Unanswered Question
Apr 6th, 2007

We have recently converted our WAN over to VPN using a 2811 at the head end and 2801s at the remote sites. Everything works fine until we have a failure of the Internet at one of the remote sites. After the Internet connection comes back up, it takes upwards of 20 minutes before the VPN tunnel re-establishes. A reboot on the 2801 takes care of the issue.



I have this problem too.

This happens when the connection is abruptly terminated. Try using clear cry isa and clear cry sa command to reset the connection once it is disconnected.
