API Guide

Usage
Information
● This command can be used to enable or disable BFD for an interface associated with OSPFv3.
Interface level BFD configuration takes precedent over the OSPF global level BFD configuration. If
there is no BFD configuration present at the interface level global OSPF BFD configuration will be
inherited. All types of interfaces are supported.
Example
(conf-if-eth1/1/1)#ipv6 ospf bfd all-neighbors
Supported
releases
10.4.2E or later
ip route bfd
Enables or disables BFD on static routes.
Syntax
ip route[vrf vrf-name] bfd [interval interval min_rx wait-time multiplier
number role {active | passive}]
Parameters
● vrf vrf-name — Enter vrf and then the name of the VRF to configure static route in that VRF.
● 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 minimum 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 simultaneously. 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 is 3.
The BFD role is active
Command Mode CONFIG
Usage
Information
Use this command to enable or disable BFD for all the configured IPv4 static routes for the specified VRF.
If you do not specify a VRF name, the command is applicable for the default VRF.
The no version of this command disables BFD on a static route
Example
OS10(config)# ip route bfd interval 250 min_rx 250 multiplier 4 role
active
Supported
releases
10.4.2E or later
ipv6 route bfd
Enables or disables BFD on IPv6 static routes.
Syntax
ipv6 route [vrf vrf-name] bfd [interval millisec min_rx min_rx multiplier
role {active | passive}]
Parameters
● vrf vrf-name — Enter the keyword VRF and then the name of the VRF to configure static route in
that VRF.
● interval milliseconds — Enter the time interval for sending control packets to BFD peers,
from 100 to 1000.
