Configuring BFD-PBR Interworking

This section describes the procedure and precautions for configuring BFD-PBR interworking.

Prerequisites

Before you configure BFD-PBR interworking, complete the following tasks on devices at both ends:

Manually configuring the static BFD session. For details, see Creating a Static BFD Session.

The static BFD session can be of the one-hop or multi-hop type.
Configuring the IP unicast PBR. For details, see Key Points for Configuring PBR.

Context

You need to configure the interworking function only on the device where the PBR function is enabled.

When the interworking function is configured and the BFD session is deleted from the remote device, the interworking function fails. In this case, the local device continues forwarding traffic based on the PBR.

Procedure

Access the system view.
```
system-view
```
Accesses the view of the PBR policy.
```
policy-based-route
```
Create a PBR rule and access its view.
```
rule name rule-name
```
Configure interworking between PBR and BFD.
```
track bfd-session local-discr-value
```
A PBR rule can interwork with either IP-link or BFD.
