Parameters
number: Number of the tunnel interface, ranging from 0 to 4095. The number of tunnels that can be
created is restricted by the total number of interfaces and the memory.
Description
Use interface tunnel to create a tunnel interface and enter its view.
Use undo interface tunnel to delete a specific tunnel interface.
By default, no tunnel interface is created on the firewall.
Use interface tunnel to enter the interface view of a specific tunnel. If the specified tunnel interface does
not exist, the system will create the interface and enter its view.
A tunnel interface number is only locally significant. Thus, the tunnel interfaces on the two ends of a
tunnel can use the same or different interface numbers.
