API Guide

NOTE: By default, OSPF uses the following BFD parameters for its neighbors: min_tx = 200 msec, min_rx = 200 msec,
multiplier = 3, role = active.
Disabling BFD for IPv6 Static Routes
To disable BFD for IPv6 static routes, use the following command.
Disable BFD for static routes.
no ipv6 route bfd
CONFIGURATION Mode
BFD commands
bfd
Enables BFD sessions with specified neighbors.
Syntax
bfd
Parameters None
Default Not configured
Command Mode
ROUTER-NEIGHBOR
ROUTER-TEMPLATE
Usage
Information
● Use the bfd command to configure BFD sessions with a specified neighbor or neighbors which inherit
a BGP template. Use the neighbor {ip-address | ipv6-address} command in ROUTER-
BGP mode to specify the neighbor. Use the template template-name command in ROUTER-
BGP mode to specify a BGP template. Use the no bfd command in ROUTER-NEIGHBOR mode to
disable BFD sessions with a neighbor.
● Use the bfd all-neighbors command to configure L3 protocol-specific BFD parameters for all
BFD sessions between discovered neighbors. The BFD parameters you configure override the global
session parameters configured with the bfd interval command.
Example
OS10(conf)# router bgp 1
OS10(config-router-bgp-1)# neighbor 10.1.1.1
OS10(config-router-neighbor)# bfd
OS10(config-router-neighbor)# no shutdown
OS10(config)# router bgp 300
OS10(config-router-bgp-300)# template ebgppg
OS10(config-router-template)# bfd
OS10(config-router-template)# exit
OS10(config-router-bgp-300)# neighbor 3.1.1.1
OS10(config-router-neighbor)# inherit template ebgppg
OS10(config-router-neighbor)# no shutdown
Supported
