ipv6 ospf bfd all-neighbors
Establish BFD sessions with all OSPFv3 neighbors on a single interface or use non-default BFD session parameters.
Syntax
ipv6 ospf bfd all-neighbors [disable | [interval interval min_rx min_rx
multiplier value role {active | passive}]]
To disable all BFD sessions on an OSPFv3 interface implicitly, use the no ipv6 ospf bfd all-neighbors
disable command in interface mode..
Parameters
disable (OPTIONAL) Enter the keyword disable to disable BFD on this interface.
interval
milliseconds
(OPTIONAL) Enter the keyword 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 keyword 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.

Usage Information
This command provides the flexibility to fine-tune the timer values based on individual interface needs when you
configure ipv6 ospf BFD in CONFIGURATION mode. Any timer values specified with this command overrides
timers set using the bfd all-neighbors command. Using the no form of this command does not disable BFD
if you configure BFD in CONFIGURATION mode.
To disable BFD on a specific interface while you configure BFD in CONFIGURATION mode, use the keyword
disable.
ipv6 ospf cost
Explicitly specify the cost of sending a packet on an interface.
