Configuring a GRE over IPv6 tunnel

NOTE:

The GRE over IPv6 tunnel configuration is available only at the CLI.

Configuration guidelines

Deleting a tunnel interface also remove the functions configured on this tunnel interface.

The source address and destination address of a tunnel uniquely identify a path. They must be

configured at both ends of the tunnel and the source address at one end must be the destination
address at the other end and vice versa.

Tunnel interfaces using the same encapsulation protocol must have different source addresses and
destination addresses.

If you configure a source interface for a tunnel interface, the tunnel interface takes the primary IP
address of the source interface as its source address.
