Usage guidelines
To create a new tunnel interface, you must specify the tunnel mode in this command. To enter the view of
an existing tunnel interface, you do not need to specify the tunnel mode.
A tunnel interface number is locally significant. The tunnel interfaces on the two ends of a tunnel can use
the same or different interface numbers.
Examples
# Create a GRE over IPv4 tunnel interface Tunnel 1 and enter tunnel interface view.
