Deployment 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.
• 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.
Defaults See Parameters.

Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
This command provides the exibility to ne-tune the timer values based on individual interface needs when you
congure the ipv6 ospf bfd command 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gured BFD in CONFIGURATION mode.
To disable BFD on a specic interface while BFD is congured in CONFIGURATION mode, use the keyword
disable.
ipv6 ospf cost
Explicitly specify the cost of sending a packet on an interface.
Syntax
ipv6 ospf interface-cost
Parameters
interface-cost
Enter a unsigned integer value expressed as the link-state metric. The range is from 1 to
65535.
