Parameters
value: Specifies the minimum interval for transmitting multi-hop BFD control packets, in milliseconds. The
value range for this argument is 100 to 1000.
Usage guidelines
Use this command to make sure that the BFD packet sending rate does not exceed the device capability.
The actual BFD control packet transmitting interval on the local end is the greater value between the
minimum interval for transmitting BFD control packets on the local end and the minimum interval for
receiving BFD control packets on the peer end.
Examples
# Configure the minimum interval for transmitting multi-hop BFD control packets as 500 milliseconds.

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.
Examples
# Configure the session establishment mode as passive.
