Is there any bug in the command "crypto isakmp keepalive 30 periodic"?
Problem is that cisco never re-establishes the tunnel within the assigned lifetime 86400.
If the other end peer?s tunnel got broken within 86400 and it tries to re-establish the connection, Cisco is not re-establishing it and our network is down for so many hours, till Cisco automatically re-establish the connections after its lifetime 86400.
How to solve this problem?

The benefit of this approach over the default approach (on-demand dead peer detection) is earlier detection of dead peers.
