Command Mode CONFIGURATION Verify that sessions have been created for static routes using the command show bfd neighbors, as shown in the example below. View detailed session information using the command show bfd neighbors detail, as shown in the example in Changing physical port session parameters.

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. 176 | Bidirectional Forwarding Detection
