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.

Table 1 Interface and IP address assignment

Device	Interface	IP address
Device A	Vlan-int10	20.1.1.1/24
	Vlan-int20	2001::1/64
	Tunnel1	3001::1/64
	Tunnel2	4001::1/64
Device B	Vlan-int10	30.1.1.1/24
	Vlan-int20	5001::1/64
	Tunnel1	3001::2/64
Device C	Vlan-int10	40.1.1.1/24
	Vlan-int20	6001::1/64
	Tunnel2	4001::2/64

 

Applicable hardware and software versions

The following matrix shows the hardware and software versions to which this configuration example is applicable:

 

Hardware	Software version
S6550X-HI switch series	Release 1116 and later
S6880 switch series	Release 1116 and later
S9820-8M switch	Release 1116 and later
S9855 switch series	Not supported
S9825 switch series	Not supported

 

Restrictions and guidelines

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

On the device, 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.
