Parameters

active: Uses the active mode. In active mode, BFD actively transmits BFD control packets to the remote device, regardless of whether it receives a BFD control packet from the remote device.

passive: Uses the passive mode. In passive mode, BFD does not actively transmit a BFD control packet to the remote end; it transmits a BFD control packet only after receiving a BFD control packet from the remote end.

Usage guidelines

At least one end must operate in active mode for a BFD session to be established.

To establish a session for BFD MAD, the system always operates in active mode. For more information about BFD MAD, see IRF Configuration Guide.
