Commands
● bfd all-neighbors — establish BFD sessions with all neighbors discovered by the IS-IS protocol or
OSPF protocol out of all interfaces.
vrrp bfd
Establish a VRRP BFD session.
Syntax
vrrp bfd {all-neighbors | neighbor ip-address} [interval interval min_rx
min_rx multiplier value role {active | passive}]
To undo your VRRP BFD configuration, use the no vrrp bfd {all-neighbors | neighbor
ip-address } [interval interval min_rx min_rx multiplier value role {active
| passive}] command.
Parameters
all-neighbors Establish BFD sessions with all BFD neighbors on an interface.
neighbor ip-
address
Enter the IP address of the BFD neighbor.
interval
milliseconds
(OPTIONAL) Enter the keyword interval to specify non-default BFD session
parameters beginning with the transmission interval. The range is 50 to 1000. The
default is 100.
min_rx
milliseconds
Enter the keyword 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 50 to
1000. The default is 100.
multiplier Enter the keyword multiplier to specify the number of packets that must be
missed in order to declare a session down. The range is 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.
