Establishing BFD Sessions with OSPFv3 Neighbors for nondefault VRFs

To configure BFD in a nondefault VRF, use the following procedure:

  • Enable BFD globally.
    CONFIGURATION mode
    bfd enable
  • Establish sessions with all OSPFv3 neighbors in a specific VRF.
    ROUTER-OSPFv3 mode
    bfd all-neighbors
  • Establish sessions with the OSPFv3 neighbors on a single interface in a specific VRF.
    INTERFACE mode
    ipv6 ospf bfd all-neighbors
  • To disable BFD on a specific OSPFv3 enabled interface, use the ipv6 ospf bfd all-neighbors disable command. You can also use the no bfd enable command to disable BFD on a specific interface.
NOTE You can create upto a maximum of 128 BFD sessions (combination of OSPFv2 and OSPFv3 with a timer of 300*300*3) for both default and nondefault VRFs.

The following example shows the configuration to establish sessions with all OSPFv3 neighbors in a specific VRF:

ipv6 router ospf 20 vrf vrf1
bfd all-neighbors
!

The following example shows the configuration to establish sessions with all OSPFv3 neighbors on a single interface in a specific VRF:

interface vlan 102
ip vrf forwarding vrf vrf1
ipv6 ospf bfd all-neighbors

The following example shows the show bfd vrf neighbors command output for nondefault VRF:
