Configuring BFD over MPLS Traffic Engineering LSPs

Enabling BFD Parameters for BFD over TE Tunnels

BFD for TE tunnel is enabled at the head-end by configuring BFD parameters under the tunnel. When BFD
is enabled on the already up tunnel, TE waits for the bringup timeout before bringing down the tunnel. BFD
is disabled on TE tunnels by default. Perform these tasks to configure BFD parameters and enable BFD over
TE Tunnels.
BFD paces the creation of BFD sessions by limiting LSP ping messages to be under 50 PPS to avoid
