Usage Guidelines

Usage Scenario

When multiple BFD sessions exist, you can view information about certain BFD sessions by specifying the parameters such as the type, name, and peer IP address.

Precautions

If a static BFD session with automatically negotiated discriminators and a dynamic BFD session share the same configurations, you can view that the shared session configurations by BFD session type (static and dynamic).
