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 exibility to ne-tune the timer values based on individual interface needs when you
congure ip 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.
To disable BFD on a specic interface while you congure BFD in CONFIGURATION mode, use the keyword
disable.
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 | [interval interval min_rx min_rx multiplier value role {active |
passive}]]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.
