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

IS-IS has been enabled using the isis 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] link-group link-a
[*HUAWEI-isis-1-link-group-link-a] quit
[*HUAWEI-isis-1] quit
[*HUAWEI] interface GigabitEthernet0/1/0
[*HUAWEI-isis-GigabitEthernet0/1/0] isis enable
[*HUAWEI-isis-GigabitEthernet0/1/0] isis link-group link-a
