Configuring BFD on MPLS TE Fast Reroute

MPLS Traffic Engineering (TE) uses BFD accelerate the detection of node failures and to provide fast
forwarding path failure detection times. BFD for MPLS TE fast reroute is configured automatically
when you enable the fast reroute on a tunnel. "See the Configuring MPLS TE Fast Reroute Link and
Node Protection" chapter in the Cisco Nexus 7000 Series NX-OS Multiprotocol Label Switching
Configuration Guide, Release 5.x for more information.
Disabling BFD on an Interface
You can selectively disable BFD on an interface for a routing protocol that has BFD enabled at the global
or VRF level.
To disable BFD on an interface, use one of the following commands in interface configuration mode:
