Hi, we have back-up IOS router on branch (spoke) with cellular UMTS card and vpn l2l to the central site (hub with ASA). We need to put down the vpn channel after a defined amount of time, with no interesting traffic.

By now we have keepalive vpn traffic that keep up the cellular line.

thank you in advance
