API Guide

Parameters
● interval milliseconds — Enter the time interval for sending control packets to BFD peers;
from 100 to 1000. Dell EMC recommends using more than 100 milliseconds.
● min_rx milliseconds — Enter the maximum waiting time for receiving control packets from BFD
peers; from 100 to 1000. Dell EMC recommends using more than 100 milliseconds.
● multiplier number — Enter the maximum number of consecutive packets that must not be
received from a BFD peer before the session state changes to Down; from 3 to 50.
● role {active | passive} — Enter active if the router initiates BFD sessions. Both BFD
peers can be active at the same time. Enter passive if the router does not initiate BFD sessions, and
only responds to a request from an active BFD to initialize a session.
Default
The time interval for sending control packets to BFD peers is 200 milliseconds.
The maximum waiting time for receiving control packets from BFD peers is 200 milliseconds.
The number of consecutive packets that must be received from a BFD peer before BFD considers it as
down is 3.
The BFD role is active.
Command Mode
● ROUTER-BGP
● ROUTER-OSPF
● ROUTER-OSPFv3
Usage
Information
● Use this command to configure BFD sessions between discovered neighbors. The BFD session
parameters you configure override the global session parameters configured with the bfd interval
command. To disable BFD and ignore the configured bfd all-neighbors settings for a specified
neighbor, use the bfd disable command in ROUTER-NEIGHBOR mode.
● To remove the configured all-neighbors settings for all BGP neighbors, enter the no version of the
command. To return to the default values, use the bfd all-neighbors command.
Example
OS10(conf-router-bgp)# bfd all-neighbors interval 250 min_rx 300
multiplier 4 role passive
Supported
releases
10.4.1.0 or later
bfd disable
Ignores the configured bfd all-neighbors settings and disables BFD for a specified neighbor.
Syntax
bfd disable
Parameters None
Default Not configured
Command Mode ROUTER-NEIGHBOR
Usage
Information
Use the neighbor ip-address command in ROUTER-BGP mode to specify a neighbor. Use the bfd
disable command to disable BFD sessions with the neighbor.
Example
OS10(conf)# router bgp 1
OS10(config-router-bgp-1)# neighbor 10.1.1.1
OS10(config-router-neighbor)# bfd disable
Supported
releases
10.4.1.0 or later
