isis ipv6 link-group

Function

The isis ipv6 link-group command binds an IS-IS IPv6 interface to an existing link group.

The undo isis ipv6 link-group command unbinds an IS-IS IPv6 interface from a link group.

By default, an IS-IS IPv6 interface is not bound to any link group.

Format

isis ipv6 [ topology topology-name ] link-group group-name [ level-1 | level-2 ]

undo isis ipv6 [ topology topology-name ] link-group [ group-name ] [ level-1 | level-2 ]

Parameters

Parameter	Description	Value
topology topology-name	Specifies the name of an IS-IS topology. After the name of an IS-IS topology is specified, the routes that travel through the member links in the link group are calculated only for this topology.	The value is a string of 1 to 31 case-sensitive characters without spaces. The value must start with a letter (a to z or A to Z, case sensitive) and can contain numbers, hyphens (-), or underlines (_). When double quotation marks are used around the string, spaces are allowed in the string.
group-name	Specifies the name of a link group.	The value is a string of 1 to 32 case-sensitive characters. When quotation marks are used around the string, spaces are allowed in the string.
level-1	Binds a Level-1 IPv6 interface to the link group.	-
level-2	Binds a Level-2 IPv6 interface to the link group. If neither level-1 nor level-2 is specified in the command, both Level-1 and Level-2 IPv6 interfaces are bound to the link group.	-

Usage Guidelines

Usage Scenario

After a link group is created in the IS-IS view, run the isis link-group or isis ipv6 link-group command to bind a specified interface to the link group for the link group to take effect.

Prerequisites

IPv6 IS-IS has been enabled using the isis ipv6 enable command, and a link group has been created using the link-group command.

Example

# Bind GigabitEthernet 0/1/0 to the link group named link-a.

<HUAWEI> system-view
[~HUAWEI] isis 1
[*HUAWEI-isis-1] ipv6 enable
[*HUAWEI-isis-1] quit
[*HUAWEI] interface GigabitEthernet0/1/0
[*HUAWEI-isis-GigabitEthernet0/1/0] isis ipv6 enable
[*HUAWEI-isis-GigabitEthernet0/1/0] isis ipv6 link-group link-a
