Introduction
This document provides IPv6 over IPv4 manual tunneling with OSPFv3 configuration examples.
Prerequisites
The configuration examples in this document were created and verified in a lab environment, and all the
devices were started with the factory default configuration. When you are working on a live network,
make sure you understand the potential impact of every command on your network.
This document assumes that you have basic knowledge of H3C IPv6 over IPv4 manual tunneling and
OSPFv3.
Example: Configuring IPv6 over IPv4 manual
tunneling with OSPFv3
Network requirements
As shown in
, in IPv6 networks, Device A, Device B, and Device C act as the gateways of the
headquarters, Branch 1, and Branch 2, respectively.
Configure IPv6 over IPv4 manual tunnels to ensure that the headquarters can communicate with the two
branches over IPv4 networks.
Configure OSPFv3 on the gateways to ensure that the following requirements are met:
•
The gateways have routes to destination IPv6 addresses through tunnel interfaces.
•
Branch 1 and Branch 2 can communicate with each other through the headquarters.
