Configuring MPLS OAM for MPLS TE tunnels
MPLS OAM only supports BFD for MPLS TE tunnel connectivity verification.
To run BFD on an MPLS TE tunnel, configure both the local and remote devices as described in

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.
