Configuring Static BFD for TE

This section describes how to configure static BFD for TE to detect faults in a TE tunnel.

Usage Scenario

If a BFD session detects a fault in a TE tunnel, the BFD module instructs VPN FRR to quickly switch traffic, which reduces the adverse impact on services.

Pre-configuration Tasks

Before configuring the static BFD for TE, configure a static CR-LSP or an MPLS TE tunnel.

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

Setting BFD Parameters on the Ingress: After setting BFD parameters on the ingress, you can use BFD sessions to monitor a TE tunnel.

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 TE: After configuring static BFD for TE, you can view configurations, such as the status of the BFD sessions.
