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.

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.
