isis ipv6 enable

Function

The isis ipv6 enable command enables the IS-IS IPv6 capability for an interface and specifies the ID of the IS-IS process to be associated with the interface.

The undo isis ipv6 enable command disables the IS-IS IPv6 capability of an interface and disassociates an IS-IS process from the interface.

By default, the IS-IS IPv6 capability is disabled on an interface.

Format

isis ipv6 enable [ process-id ]

undo isis ipv6 enable

Usage Guidelines

Usage Scenario

After completing the configuration of an IS-IS process in the system view, enable IS-IS IPv6 on the interface that runs IS-IS and associate the interface with the IS-IS process using the isis ipv6 enable command.

Prerequisites

The following steps have been performed:

Enable IPv6 globally using the ipv6 command in the system view.
Enable an IS-IS process using the isis command and configure a network entity title (NET) for the device running IS-IS using the network-entity command.
Enable IPv6 for the IS-IS process using the ipv6 enable (IS-IS) command in the IS-IS view.
Enable IPv6 and configure an IPv6 address using the ipv6 enable command on each interface that runs the IS-IS process.

Precautions

An interface can be associated with only one IS-IS process.

To perform IPv6-related IS-IS configurations, you must enable IPv6 first.

Example

# Create IS-IS process 1, enable the IPv6 capability, and activate the IPv6 capability on VLANIF 10.

<HUAWEI> system-view

[HUAWEI] interface vlanif 10

[HUAWEI-Vlanif10] ipv6 enable

[HUAWEI-Vlanif10] ipv6 address fc00:0:0:2::1/64

[HUAWEI-Vlanif10] isis ipv6 enable 1

# Create IS-IS process 1, enable the IPv6 capability, and activate the IPv6 capability on GE0/0/1.
