On L2L VPN tunnel, I am getting "MM_WAIT_MSG2" through pahse 1 checking command "sh crypto isakmp sa" for a specific tunnel which is not up. What can be the possible debugging which can be done?
Disconnection of the tunnel is caused by a network issue, we need to configure DPD (DeadPeerDetection) to make sure that whenever one side of the connection goes down, the other side realises about the disconnetion and restarts the tunnel.
