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.
