bfd all-interfaces enable (RIP view)

Function

The bfd all-interfaces enable command enables BFD on all the interfaces in a RIP process.

The undo bfd all-interfaces enable command disables BFD from all the interfaces in a RIP process.

By default, BFD is disabled in a RIP process.

Usage Guidelines

Usage Scenario

As technologies develop, voice, video, and other video on demand (VoD) services are widely applied. These services are sensitive to packet loss and delay. RIP-capable devices detect neighbor status by exchanging Update packets periodically. By default, a local device cannot detect a link failure until 180s after the link failure occurs. During this period, carriers or users may suffer the loss of a large number of packets. To address this problem, configure BFD.

The bfd all-interfaces enable command enables BFD for RIP, which speeds up fault detection and route convergence.

Prerequisites

Before running this command, ensure the following operations have been performed:

Global BFD has been enabled using the bfd command.
A RIP process has been created and the RIP view has been displayed using the rip command.

Precautions

The BFD priority set using the rip bfd enable command in the interface view is higher than the one set using the bfd all-interfaces enable command.

If the rip bfd block command has been run on a RIP-capable interface, the bfd all-interfaces enable command does not take effect. In this situation, run the rip bfd enable command to enable BFD.

Example

# Enable BFD on all interfaces in a RIP process.

<HUAWEI> system-view
[~HUAWEI] bfd
[*HUAWEI-bfd] quit
[*HUAWEI] rip
[*HUAWEI-rip-1] bfd all-interfaces enable
