Changing static route session parameters BFD sessions are configured with default intervals and a default role. The parameters that can be configured 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: Step 1 Task Command Syntax Change parameters for all static route sessions. ip route bfd interval milliseconds min_rx milliseconds multiplier value role [active | passive] Command Mode CONFIGURATION View session parameters using the command show bfd neighbors detail, as shown in the example in Verifying BFD sessions with BGP neighbors using show bfd neighbors detail. Disabling BFD for static routes If BFD is disabled, 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 (Message 3). To disable BFD for static routes: Step 1 Task Disable BFD for static routes. Command Syntax no ip route bfd Command Mode CONFIGURATION Configuring BFD for OSPF e c BFD for OSPF is only supported on platforms: S4820T When using BFD with OSPF, the OSPF protocol registers with the BFD manager on the RPM. BFD sessions are established with all neighboring interfaces participating in OSPF. If a neighboring interface fails, the BFD agent on the line card notifies the BFD manager, which in turn notifies the OSPF protocol that a link state change occurred.
