number: Number of encapsulations in a tunnel, in the range 1 to 10.

Use the encapsulation-limit command to configure the maximum number of 
encapsulations on a tunnel.

Use the undo encapsulation-limit command to remove the configuration.

By default, the maximum encapsulation limit is 4.

The encapsulation limit applies to only IPv6 over IPv6 tunnels.

# Configure the encapsulation limit on a tunnel to 3.
