Configuring BFD for LSPs
To configure BFD for an LSP, configure both the local and remote devices as described in Table 36.
Table 36 Configurations on the local and remote devices
BFD session
establishment
mode
Node type
Execute the "mpls
bfd enable"
command?
Execute the
"mpls bfd"
command?
Configure the

keyword?
Static mode
Local Yes Yes Yes
Remote Yes Yes Yes
Dynamic mode
Local Yes Yes No
Remote Yes No N/A
Follow these guidelines to configure BFD for an LSP 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
configuring BFD for the LSP tunnel, configure an MPLS LSR ID for the local device and make
sure a route is available on the remote device to reach the MPLS LSR ID.
• If multiple LSPs exist for an FEC, you can perform one of the following tasks:
 Create a BFD session for an LSP by specifying the next hop of the LSP.
 Create a BFD session for each LSP without specifying a next hop.
• 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.
