interface tunnel number

undo interface tunnel number

System view

number: Number of a tunnel interface, in the range 0 to 1023. The volume of 
tunnels is subject to the total number of interfaces and the capacity of memory.

Use the interface tunnel command to create a tunnel interface and enter tunnel 
interface view.

Use the undo interface tunnel command to remove a tunnel interface.

By default, there is no tunnel interface on the device.

■

Executing the interface tunnel command, you enter tunnel interface view if 
the tunnel interface exists.

■

A tunnel interface number has only local significance. Therefore, both ends of a 
tunnel can have the same interface number or different interface numbers.

keepalive [ seconds [ times ] ]

Tunnel interface view

seconds: Interval between transmitting keepalive packets, in the range 1 to 
32,767 seconds. The default value is 10.

times: Maximum number of attempts for transmitting a keepalive packet, in the 
range 1 to 255. The default value is 3.

Use the keepalive command to enable the GRE keepalive function to detect the 
status of the tunnel interfaces and set the keepalive interval and the maximum 
number of attempts for transmitting a keepalive packet.
