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 100.
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 100. The
default is 100.
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 — The active system initiates the BFD session. Both systems can be
active for the same session.
• Passive — The 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 exibility to ne-tune the timer values based on individual interface needs when
you congure ipv6 ospf BFD in CONFIGURATION mode. Any timer values specied 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 congure BFD in CONFIGURATION mode.
