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}]]
Parameters
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:50-100
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
