Version 9.2.0.0 Introduced on the Z9000, S4820T, and S4810.
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.
isis bfd all-neighbors
Enable BFD on all IS-IS neighbors discovered on an interface.
S4820T
Syntax
isis bfd all-neighbors [disable | [interval interval min_rx
min_rx multiplier value role {active | passive}]]
To remove all BFD sessions with IS-IS neighbors discovered on this interface, use the no
isis bfd all-neighbors [disable | [interval interval min_rx
min_rx multiplier value role {active | passive}]] command.
Parameters
disable (OPTIONAL) Enter the keyword disable to disable BFD on this
interface.
interval
milliseconds
(OPTIONAL) Enter the keywords 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 1000. The default is 100.
multiplier value Enter the keywords 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.
