IPv6 Tunneling Feature Overview and Configuration Guide

IPv6 Tunneling is a mechanism for encapsulating IPv4 and IPv6 packets within a site-to-site IPv6 VPN. It is used to form a virtual point-to-point link between two IPv6 nodes. IPv6 Tunnels are stateless and have no knowledge of the configuration or even existence of the remote tunnel endpoint. Once an IPv6 Tunnel is configured, packets are encapsulated and forwarded regardless of whether the decapsulating device is present or not.

IPv6 Tunneling allows hosts in one private IP network to communicate with hosts in another private IP network by providing a tunnel between two routers across the Internet. The IPv6 tunnel connection endpoints are terminated via a Virtual Tunnel Interface (VTI) configured in each device.

This guide describes IPv6 Tunneling and how to configure it on AlliedWare Plus™ devices.
