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 200 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:
Dell#show bfd vrf vrf1 neighbors
