Introduction
6rd is a IPv6 transitioning mechanism to allow for stateless tunneling of IPv6 over IPv4. It is intended as a mechanism to tunnel across an ISP's IPv4 only access network.
This example shows the configuration of a 6rd Border Relay (BR) and the configuration of the corresponding 6rd Customer Edge (CE) router. 6rd is specified in RFC5969.
