and remote devices, but the mpls bfd command is not needed on the remote PE. A dynamic BFD
session verifies the connectivity of a unidirectional LSP tunnel from the local device to the remote
device.
The source address of the BFD session is the MPLS LSR ID of the local device. Before configuring BFD for
the LSP tunnel, perform the following tasks:
1. Configure an MPLS LSR ID for the local device.
2. Make sure a route is available on the remote device to reach the MPLS LSR ID.
Examples
# Use BFD to verify the connectivity of the LSPs to destination 22.22.2.2/32.
<Sysname> system-view
[Sysname] mpls bfd 22.22.2.2 32
# Use BFD to verify the connectivity of the LSP with destination address 22.22.2.2/32 and next hop
address 12.0.0.2.

# Use BFD to verify the connectivity of the LSP with destination address 22.22.2.2/32 and next hop
address 12.0.0.2, set the local and remote discriminators both to 1, and reference the BFD session
