Generic Packet Tunneling in IPv6 Specification

RFC 2473            Generic Packet Tunneling in IPv6       December 1998


   original header

        the header of an original packet.

   tunnel

        a forwarding path between two nodes on which the payloads of
        packets are original packets.

   tunnel end-node

        a node where a tunnel begins or ends.

   tunnel header

        the header prepended to the original packet during
        encapsulation.  It specifies the tunnel end-points as source and
        destination.

   tunnel packet

        a packet that encapsulates an original packet.

   tunnel entry-point

        the tunnel end-node where an original packet is encapsulated.

   tunnel exit-point

        the tunnel end-node where a tunnel packet is decapsulated.

   IPv6 tunnel

        a tunnel configured as a virtual link between two IPv6 nodes, on
        which the encapsulating protocol is IPv6.

   tunnel MTU

        the maximum size of a tunnel packet payload without requiring
        fragmentation, that is, the Path MTU between the tunnel entry-
        point and the tunnel exit-point nodes minus the size of the
        tunnel header.

   tunnel hop limit

        the maximum number of hops that a tunnel packet can travel from
        the tunnel entry-point to the tunnel exit-point.
