DETAILED STEPS
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:
Command Purpose
Step 1
configure terminal
Example:
switch# configure terminal
switch(config)#
Enters configuration mode.
Step 2
vrf context vrf-name
Example:
switch(config)# vrf context Red
switch(config-vrf)#
(Optional) Enters VRF configuration mode.
Step 3
ip route route interface {nh-address |
nh-prefix}
Example:
switch(config-vrf)# ip route 192.0.2.1
ethernet 2/1 192.0.2.4
Creates a static route Use the ? keyword to display the
supported interfaces.
Step 4
ip route static bfd interface
{
nh-address | nh-prefix}
Example:
switch(config-vrf)# ip route static bfd
ethernet 2/1 192.0.2.4
Enables BFD for all static routes on an interface. Use
the ? keyword to display the supported interfaces.
Step 5
show ip route static[vrf vrf-name]
Example:
switch(config-vrf)# show ip route static
vrf Red
(Optional) Displays the static routes.
Step 6
copy running-config startup-config
Example:
switch(config-vrf)# copy running-config
startup-config
(Optional) Saves this configuration change.
