ipv6 route bfd
Enable BFD for all IPv6 neighbors configured through static routes.
Syntax
ipv6 route bfd [vrf vrf-name] [prefix-list prefix-list-name] [interval interval
min_rx min_rx multiplier value role {active | passive}]
To disable BFD for all IPv6 neighbors configured through static routes, use the no ipv6 route bfd [vrf
vrf-name] [prefix-list prefix-list-name] [interval interval min_rx min_rx
multiplier value role {active | passive}] command.
Parameters
vrf vrf-name (Optional) Enter the keyword vrf and then the name of the VRF to enable or disable
BFD on the next-hop IPv6 neighbor corresponding to that VRF.
prefix-list prefix-
list-name
(Optional) Enter the keyword prefix-list followed by the name of the prefix list to
enable or disable BFD on specific IPv6 neighbors.
interval
milliseconds
(OPTIONAL) Enter the keywords interval to specify non-default BFD session
parameters beginning with the transmission interval. The range is from 50 to 1000. The
default is 200.
min_rx
milliseconds
Enter the keywords min_rx to specify the minimum rate at which the local system
receives control packets from the remote system. The range is from 50 to 1000. The
default is 200.
multiplier value Enter the keywords multiplier to specify the number of packets that must be missed
in order to declare a session down. The range is from 3 to 50. The default is 3.
role [active |
passive]
Enter the role that the local system assumes:
• Active — active system initiates the BFD session. Both systems can be active for
the same session.
• Passive — passive system does not initiate a session. It only responds to a request
for session initialization from the active system.
The default is Active.
Defaults See Parameters.

ip ospf bfd all-neighbors
Establish BFD sessions with all OSPF neighbors on a single interface or use non-default BFD session parameters.
Syntax
ip ospf bfd all-neighbors [disable | [interval interval min_rx min_rx
multiplier value role {active | passive}]]
To disable all BFD sessions on an OSPF interface implicitly, use the no ip ospf bfd all-neighbors
disable command in interface mode..
