I'm setting a vpn lab and there is one thing I don't really understand from show crypt isakmp sa output.
The HQ router (10.0.0.1) is terminating all vpn connections. However I need a clarification about dst and src columns in the following output.
Why 10.0.0.1 is either in dst or src column? What does it mean?
HQ#show crypto isakmp sa dst src state conn-id slot status
10.0.0.1 192.168.1.1 QM_IDLE 945 0 ACTIVE
10.0.0.1 192.168.2.1 QM_IDLE 1443 0 ACTIVE
192.168.3.1 10.0.0.1 QM_IDLE 701 0 ACTIVE
10.0.0.1 192.168.4.1 QM_IDLE 1435 0 ACTIVE
