Command Syntax bfd enable Command Mode INTERFACE Configuring BFD for Static Routes Configuring BFD for Static Routes is supported on the S5000 platform. BFD gives systems a link state detection mechanism for static routes. With BFD, systems are notified to remove static routes from the routing table as soon as the link state change occurs, rather than having to wait until packets fail to reach their next hop. Configuring BFD for static routes is a three-step process: 1. Enabling BFD globally. 2. On the local system, establish a session with the next hop of a static route. Refer to Configuring BFD for Static Routes. 3. On the remote system, establish a session with the physical port that is the origin of the static route. Refer to Establishing a session on physical ports. Related configuration tasks • Changing static route session parameters. • Disabling BFD for static routes. Establishing sessions for static routes Sessions are established for all neighbors that are the next hop of a static route. 158 | Bidirectional Forwarding Detection (BFD)
