1. Introduction
This document explains how IPv6 options [RFC8200] can be used in IPv6
tunnels. It also defines the IPv6 Tunnel Payload Forwarding (TPF)
option.
An IPv6 tunnel [RFC2473] connects two nodes, called the entry-point
and the exit-point. The entry-point receives a packet and
encapsulates it in a Tunnel IPv6 Header. Figure 1 depicts the
encapsulation.
