Default Not configured Command Mode ROUTER-NEIGHBOR Usage Information Use the neighbor ip-address command in ROUTER-BGP mode to specify a neighbor. Use the bfd disable command to disable BFD sessions with the neighbor. Example OS10(conf)# router bgp 1 OS10(config-router-bgp-1)# neighbor 10.1.1.1 OS10(config-router-neighbor)# bfd disable Supported releases 10.4.1.0 or later bfd enable Enables BFD on all interfaces on the switch. Syntax bfd enable Parameters None Default BFD is disabled. Command Mode CONFIGURATION Usage Information Before you configure BFD for static routing or a routing protocol, enable BFD globally on each router in a BFD session. To globally disable BFD on all interfaces, enter the no bfd enable command. Example OS10(config)# bfd enable Supported releases 10.4.1.0 or later bfd interval Configures parameters for all BFD sessions on the switch. Syntax Parameters bfd interval milliseconds min_rx milliseconds multiplier number role {active | passive} • 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. • multiplier number - Enter the number of consecutive packets that can be missed 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. The number of consecutive packets that must be received from a BFD peer is 3. The BFD role is active. Command Mode CONFIGURATION Usage Information Use this command to configure global BFD session settings. To configure the BFD parameters used in sessions established with neighbors discovered by an L3 protocol, use the bfd all-neighbors command. The no version of this command deletes the configured global settings and returns to the default values. 548 Layer 3
