R3721-F3210-F3171-HP High-End Firewalls VPN Command Reference-6PW101

You can select a tunnel mode according to the actual network topology and application. The two ends

of a tunnel must have the same tunnel mode specified; otherwise, traffic transmission may fail.

Only one automatic tunnel can be created at the start point of a tunnel.
