Bidirectional Forwarding Detection (BFD) | 271
isis bfd all-neighbors
e
Enable BFD on all IS-IS neighbors discovered on an interface.
Syntax
isis bfd all-neighbors [disable | [interval interval min_rx min_rx multiplier value role {active |
passive}]]
Remove all BFD sessions with IS-IS neighbors discovered on this interface using the command no isis
bfd all-neighbors [disable | [interval interval min_rx min_rx multiplier value role {active |
passive}]].

Usage
Information
This command provides the flexibility to fine tune the timer values based on individual interface needs
when ISIS BFD is configured in CONFIGURATION mode. Any timer values specified with this
command override timers set using the command bfd neighbor. Using the no form of this command
will not disable BFD if BFD is configured in CONFIGURATION mode.
Use the keyword disable to disable BFD on a specific interface while BFD is configured in from
CONFIGURATION mode.
disable (OPTIONAL) Enter the keyword disable to disable BFD on this interface.
interval milliseconds
(OPTIONAL) Enter this keyword to specify non-default BFD session
parameters beginning with the transmission interval.
Range:50-1000
Default:100
min_rx milliseconds
Enter this keyword to specify the minimum rate at which the local system
would like to receive control packets from the remote system.
Range:50-1000
Default:100
multiplier value
Enter this keyword to specify the number of packets that must be missed in
order to declare a session down.
Range:3-50
Default: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.
Default: Active
