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.

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
