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

Example: switch(config-vrf)# copy running-config startup-config 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: 5-24 Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide, Release 5.x OL-23435-03
