Configuring node fault detection

Perform this task to configure the RSVP hello mechanism or BFD on the PLR and the protected node to detect the node faults caused by signaling protocol faults. FRR does not need to use the RSVP hello mechanism or BFD to detect the node faults caused by the link faults between the PLR and the protected node.

You do not need to perform this task for FRR link protection.

To configure node fault detection:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enter interface view of the connecting interface between the PLR and the protected node.	interface interface-type interface-number	N/A
3. Configure node fault detection.	(Method 1) Enable RSVP hello extension on the interface:rsvp hello enable (Method 2) Enable BFD on the interface:rsvp bfd enable	Use either method. By default, RSVP hello extension is disabled, and BFD is not configured. For more information about the rsvp hello enable command and the rsvp bfd enable command, see "Configuring RSVP."

3. Configure node fault detection.

(Method 1) Enable RSVP hello extension on the interface:rsvp hello enable
(Method 2) Enable BFD on the interface:rsvp bfd enable

Use either method.

By default, RSVP hello extension is disabled, and BFD is not configured.
