Configuring Static BFD for CR-LSP

By configuring static BFD for CR-LSP, you can monitor a static CR-LSP or an RSVP CR-LSP.

Usage Scenario

BFD for CR-LSP monitors the primary and hot-standby CR-LSPs and triggers traffic switchovers between them.

When static BFD for CR-LSP is used and the BFD status is Up, the BFD status remains Up even after the tunnel interface of the CR-LSP is shut down.

Pre-configuration Tasks

Before configuring static BFD for CR-LSP, configure an RSVP-TE tunnel or CR-LSP backup.

Enabling BFD Globally

BFD must be enabled globally before configurations relevant to BFD are performed.

Setting BFD Parameters on the Ingress

This section describes how to set BFD parameters on the ingress to monitor CR-LSPs using BFD sessions.

Setting BFD Parameters on the Egress

This section describes how to set BFD parameters on the egress to monitor CR-LSPs using BFD sessions.

Verifying the Configuration of Static BFD for CR-LSP

After configuring the static BFD for CR-LSP, you can view configurations, such as the status of the BFD sessions of Up.
