OR Configure BFD sessions with all neighbors discovered by the BGP in ROUTER-BGP mode. The BFD session parameters you configure override the global session parameters configured in Step 1. 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 100 to 1000; default 200. 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; default 200. Dell EMC recommends using more than 100 milliseconds. • multiplier number - Enter the maximum number of consecutive packets that are not received from a BFD peer before the session state changes to Down, from 3 to 50; default 3. • 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. The default is active. To ignore the configured bfd all-neighbors settings for a specified neighbor, enter the bfd disable command in ROUTERNEIGHBOR mode. OR Enter a BGP template with neighborhood name in ROUTER-BGP mode. Configure BFD sessions with all neighbors which inherit the template in ROUTER-TEMPLATE mode. For more information on how to use BGP templates, see Peer templates. The global BFD session parameters configured in Step 1 are used. template template-name bfd no shutdown 4 Verify the BFD for BGP configuration in EXEC mode. show bfd neighbors [detail] BFD for BGP all-neighbors configuration OS10(conf)# bfd interval 200 min_rx 200 multiplier 6 role active OS10(conf)# bfd enable OS10(conf)# router bgp 4 OS10(config-router-bgp-4)# bfd all-neighbors interval 200 min_rx 200 multiplier 6 role active BFD for BGP single-neighbor configuration OS10(conf)# bfd interval 200 min_rx 200 multiplier 6 role active OS10(conf)# bfd enable OS10(conf)# router bgp 1 OS10(config-router-bgp-1)# neighbor 150.150.1.1 OS10(config-router-neighbor)# bfd OS10(config-router-neighbor)# no shutdown BFD for BGP template configuration 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 Display BFD operation OS10# show bfd neighbors * - Active session role LocalAddr RemoteAddr Interface State Rx-int Tx-int Mult VRF Clients 288 Layer 3
