Configuring Static BFD to Monitor an LDP LSP

Configuring Static BFD to Monitor an LDP LSP

Static bidirectional forwarding detection (BFD) can be configured to detect faults in 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.
