Introduction

The following information provides IPv6 manual tunnel with OSPFv3 configuration examples.

Prerequisites

The following information applies to Comware 9-based routers. Procedures and information in the examples might be slightly different depending on the software or hardware version of the routers.

The configuration examples 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.

The following information is provided based on the assumption that you have basic knowledge of IPv6 over IPv4 manual tunneling and OSPFv3.

Example: Configuring an IPv6 over IPv4 manual tunnel with OSPFv3

Network configuration

As shown in Figure 1, IPv6 is deployed in the headquarters (HQ) and its branches and they are connected through an IPv4 network. Device A, Device B, and Device C are gateways of the HQ, Branch 1, and Branch 2, respectively. Configure an IPv6 over IPv4 manual tunnel between the HQ and each branch B so the IPv6 networks of the HQ and branch can reach each other over the IPv4 network. Configure OSPFv3 so that the gateway devices can have routes to reach the destination IPv6 addresses through the tunnels, and the branches can communicate with each other through the HQ.

Table 1 Interface and address assignment

Device	Interface	IP address	Device	Interface	IP address
Device A	GE1/0/1	20.1.1.1/24	Device B	GE1/0/1	30.1.1.1/24
	GE1/0/2	2001::1/64		GE1/0/2	5001::1/64
	Tunnel1	3001::1/64		Tunnel1	3001::2/64
	Tunnel2	4001::1/64
Device C	GE1/0/1	40.1.1.1/24
	GE1/0/2	6001::1/64
	Tunnel2	4001::2/64

 

Software versions used

This configuration example was created and verified on R9141P16 of the MSR2630E-X1 device.

Procedures

Before you perform the following configuration, make sure the gateway devices have IPv4 connectivity to each other.

Configuring IPv6 over IPv4 manual tunnels

1.     Configure Device A:

# Assign an IP address to interface GigabitEthernet 1/0/1.

[DeviceA] interface gigabitethernet 1/0/1

# Assign IP addresses to other interfaces on Device A in the same way. (Details not shown.)

# Create IPv6 over IPv4 manual tunnel interface Tunnel 1.

[DeviceA] interface tunnel 1 mode ipv6-ipv4

# Assign an IPv6 address to interface Tunnel 1.

[DeviceA-Tunnel1] ipv6 address 3001::1/64

# Configure the source interface of Tunnel 1 as GigabitEthernet 1/0/1. (The IP address of the source interface will be used as the source IP address of the IPv4 packets after encapsulation.)

[DeviceA-Tunnel1] source gigabitethernet 1/0/1

# Configure the destination IP address of Tunnel 1. (The specified IP address will be used as the destination IP address of the IPv4 packets after encapsulation.)
