To run BFD on an MPLS TE tunnel, configure both the local and remote devices as described
in T able 35.

Follow these guidelines to configure BFD for an MPLS TE tunnel:
•
To establish a static BFD session, ensure that the local and remote discriminators configured
locally are identical with the remote and local discriminators configured on the remote device,
respectively.
•
The source address of the BFD session is the MPLS LSR ID of the local device. Before you
configure BFD for the LSP tunnel, configure an MPLS LSR ID for the local device. Make sure a
route is available on the remote device to reach the MPLS LSR ID.
•
On a BFD session established in static mode, the ingress node and egress node both operate
in active mode. On a BFD session established in dynamic mode, the egress node operates in
active mode and the ingress node operates in passive mode. Executing the bfd session
init-mode command on the ingress or egress node does not change the node's operating
mode.
•
If both BFD and FRR are enabled for an MPLS TE tunnel, set the BFD detection interval for
tunnel connectivity verification to be longer than that for FRR. Otherwise, the BFD session for
MPLS TE tunnel connectivity verification will be down during an FRR switchover.
To configure BFD for MPLS TE tunnels:
Step
1. Enter system view.
2. Enable BFD for MPLS.
3. Enter the view of the MPLS
TE tunnel interface.
4. Configure BFD to verify
MPLS TE tunnel
connectivity.
