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
releases
10.4.1.0 or later
bfd all-neighbors
Configures parameters of BFD sessions that are established between neighbors discovered by an L3 protocol.
Syntax
bfd all-neighbors [interval milliseconds min_rx milliseconds multiplier
number role {active | passive}]
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.
