BFD configuration Before you configure BFD for a routing protocol, first enable BFD globally on both routers in the link. BFD is disabled by default. • OS10 supports: • 64 BFD sessions at 100 minimum transmit and receive intervals with a multiplier of 4 • 100 BFD sessions at 200 minimum transmit and receive intervals with a multiplier of 3 • OS10 does not support Demand mode, authentication, and Echo function. • OS10 does not support BFD on multi-hop and virtual links. • OS10 supports protocol liveness only for routing protocols. • OS10 BFD supports only the BGP routing protocol. For IPv4 and IPv6 BGP, OS10 supports only the default virtual routing and forwarding (VRF). Configure BFD globally Before you configure BFD for static routing or a routing protocol, configure BFD globally on each router, including the global BFD session settings. BFD is disabled by default. 1. Configure the global BFD session parameters in CONFIGURATION mode. 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. The default is 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. The is default 200. Dell EMC recommends using more than 100 milliseconds. • multiplier number - Enter the number of consecutive packets that must not be received from a BFD peer before the session state changes to Down, from 3 to 50. The default is 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. Layer 3 495
