CONFIGURATION Mode
BFD commands
bfd
Enables BFD sessions with specied neighbors.
Syntax
bfd
Parameters None
Default Not congured
Command Mode
ROUTER-NEIGHBOR
ROUTER-TEMPLATE
Usage Information
• Use the bfd command to congure BFD sessions with a specied 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 congure L3 protocol-specic BFD parameters for all BFD
sessions between discovered neighbors. The BFD parameters you congure override the global session
parameters congured 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
Congures all BFD session parameters established between neighbors discovered by an L3 protocol.
Syntax
bfd all-neighbors [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.
