CLI Guide

To disable all BFD sessions on an OSPFv3 interface implicitly, use the no ipv6
ospf bfd all-neighbors disable command.
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 would like to receive 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.

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 the ipv6 ospf bfd command 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 configured BFD in CONFIGURATION mode.
To disable BFD on a specific interface while BFD is configured in CONFIGURATION
mode, use the keyword disable.
