Configuring Static BFD to Monitor an LDP LSP

Usage Scenario

BFD implements fast detection at the millisecond level. To enable a device to rapidly monitor whether LDP LSPs are faulty, establish BFD sessions.

When configuring static BFD to monitor an LDP LSP, note the following:

• You can bind a BFD session to an LDP LSP only on the ingress.

• An LDP LSP to be monitored by static BFD can be established only using host routes.

Pre-configuration Tasks

Before configuring static BFD to monitor an LDP LSP, complete the following tasks:

• Configure network layer parameters to implement network layer connectivity.

• Enable MPLS LDP on each node and set up an LDP session.

• Configure an LDP LSP.
