Usage Guidelines

Usage Scenario

In static BFD, BFD session parameters are set manually to deliver requests for BFD session establishment, which can fast detect link faults. The isis bfd static command can be used to enable static BFD on an interface and set up a static BFD session on corresponding links.

Prerequisites

BFD has been enabled globally, and a specified interface has been bound to an IS-IS process using the isis enable command.

Precautions

If the isis bfd block, isis bfd enable, and isis bfd static commands are run, only the last command takes effect.

Example

# Configure static BFD on GE 0/1/0.

<HUAWEI> system-view
[~HUAWEI] isis 1
[*HUAWEI-isis-1] quit
[*HUAWEI] interface GigabitEthernet0/1/0
[*HUAWEI-GigabitEthernet0/1/0] isis enable 1
[*HUAWEI-GigabitEthernet0/1/0] isis bfd static
