Changing Static Route Session Parameters BFD sessions are configured with default intervals and a default role. The parameters you can configure are: Desired TX Interval, Required Min RX Interval, Detection Multiplier, and system role. These parameters are configured for all static routes. If you change a parameter, the change affects all sessions for static routes. To change parameters for static route sessions, use the following command . • Change parameters for all static route sessions. CONFIGURATION mode ip route bfd interval milliseconds min_rx milliseconds multiplier value role [active | passive] To view session parameters, use the show bfd neighbors detail command, as shown in the examples in Displaying BFD for BGP Information. Disabling BFD for Static Routes If you disable BFD, all static route BFD sessions are torn down. A final Admin Down packet is sent to all neighbors on the remote systems, and those neighbors change to the Down state. To disable BFD for static routes, use the following command. • Disable BFD for static routes. CONFIGURATION mode no ip route bfd Configure BFD for OSPF When using BFD with OSPF, the OSPF protocol registers with the BFD manager. BFD sessions are established with all neighboring interfaces participating in OSPF. If a neighboring interface fails, the BFD 160 Bidirectional Forwarding Detection (BFD)
