Example for Configuring Basic IS-IS IPv6 Functions

Example for Configuring Basic IS-IS IPv6 Functions

This section describes how to configure basic IS-IS IPv6 functions, including enabling IPv6 globally, configuring an IPv6 address and enabling IPv6 for each interface, and configuring basic IS-IS functions and enabling IPv6.

Networking Requirements

In Figure 9-21:

  • Device A, Device B, Device C, and Device D belong to the same AS. It is required that IS-IS run on them to implement IPv6 interworking.

  • Device A, Device B, and Device C belong to Area 10, and Device D belongs to Area 20.

  • Device A and Device B are Level-1 devices; Device C is a Level-1-2 device; Device D is a Level-2 device.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Enable the IPv6 forwarding capability on each ME device, and configure an IPv6 address for each interface.

  2. Enable IS-IS, configure the level, and specify the NET on each ME device.

Data Preparation

To complete the configuration, you need the following data:

  • IPv6 addresses of the interfaces on Device A, Device B, Device C, and Device D

  • AS numbers of Device A, Device B, Device C, and Device D

  • Levels of Device A, Device B, Device C, and Device D

Procedure

  1. Enable IPv6, and configure an IPv6 address for each interface. Use the command output on Device A as an example. The configurations of the other three ME devices are the same as that of Device A. For configuration details, see Configuration Files in this section.

  2. Configure IS-IS.

    [*DeviceD] interface gigabitethernet 2/0/0
    [*DeviceD-GigabitEthernet2/0/0] isis ipv6 enable 1
    [*DeviceD-GigabitEthernet2/0/0] commit
    [~DeviceD-GigabitEthernet2/0/0] quit
