We have site to site VPN ( L-2-L) between two locations over internet. We have Cisco ASA 5500 series and other side has some another device on which VPN tunnel is terminating.
Suddenly existing VPN tunnel has gone down due to some reason.( Pre share key , or any other algorithm)
How do we debug the VPN site to site VPN.
When i have given command
show crypto isakmp sa
it shows :
State : MM_WAIT_MSG2 and then it goes off.
when given debug command it shows :
"Removing peer from peer table failed, no Match! IP : OtherEnd.Peer.IP, Error: Unable to remove PeerTblEntry.
Please share the eperience.
Any link of cisc.com is highly appreciable.
