Symptom
There is an existent dynamic VPN configuration and as new one is added.
By adding a new Dynamic hub-and-spoke topology, the default preshared key under the DefaultL2LGroup tunnel-group is updated accordingly.
Conditions
There should be at least one Dynamic VPN configured already.
Workaround
No workaround has been found.
Further Problem Description
All existing dynamic tunnels may go down due to a PSK mismatch if a new manual PSK is configured.
