Configure BFD for OSPFv2 Globally in a Non-default VRF Instance

In non-default VRF instances, BFD for OSPFv2 can be configured globally on interfaces where BFD is enabled.

1. Access global configuration mode.
   

   device# configure terminal

2. Access OSPF router configuration mode and specify the non-default VRF instance.
   

   device(config)# router ospf vrf red

   This example accesses non-default VRF "red."
3. Enable BFD globally.
   

   device(config-router-ospf-vrf-red)# bfd 

4. Specify the interval after which routes are withdrawn after a BFD session is declared down.
   

   device(config-router-ospf-vrf-red)# bfd holdover-interval 12   

   This example specifies a holdover interval of 12 seconds.
