BFD conguration
Before you congure BFD for a routing protocol, rst 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).
Congure BFD globally
Before you congure BFD for static routing or a routing protocol, congure BFD globally on each router, including the global BFD session
settings. BFD is disabled by default.
1 Congure the global BFD session parameters in CONFIGURATION mode.

• 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.
