ISATAP tunnels are mainly used for communication between IPv6 routers or between an IPv6 host
and an IPv6 router over an IPv4 network.

Configuring a tunnel interface
Configure a Layer 3 virtual tunnel interface on each device on a tunnel so that devices at both ends can
send, identify, and process packets from the tunnel.
When an active/standby switchover occurs or the standby card is removed, the tunnel interfaces
configured on the active or standby card still exist. To delete a tunnel interface, use the undo interface
tunnel command.
To configure a tunnel interface:
