BFD commands bfd Enables BFD sessions with specified neighbors. Syntax Parameters Default Command Mode bfd None Not configured 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 ROUTERBGP mode to specify the neighbor. Use the template template-name command in ROUTERBGP 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 Supported releases 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 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 Parameters bfd all-neighbors [interval milliseconds min_rx milliseconds multiplier number role {active | passive}] ● interval milliseconds - Enter the time interval for sending control packets to BFD peers; from 50 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 50 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. Layer 3 607
