13-IPv6 over IPv4 Manual Tunneling with OSPFv3 Configuration Examples

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 HP IPv6 over IPv4 manual tunneling and OSPFv3.

Example: Configuring IPv6 over IPv4 manual tunneling with OSPFv3

Network configuration

As shown in Figure 1, 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 the following:

·     The gateways have routes to destination IPv6 addresses through tunnel interfaces.

·     Branch 1 and Branch 2 can communicate with each other through the headquarters.

Restrictions and guidelines

For tunnel interfaces to send and receive packets, you must configure a tunnel-type service loopback group.

On the S6520XE-HI switch series, a tunneled packet cannot be directly routed based on its destination address. It is sent to a tunnel-type service loopback group, which then delivers the packet to the forwarding module for Layer 3 forwarding.

Procedures

Make sure the gateways can reach each other at IPv4.
