Bidirectional Forwarding Detection

When selected, enables bidirectional forwarding detection (BFD).
Interval (ms) The interval at which the Engine sends BFD control packets. The default is 1800 milliseconds.
Min RX (ms) The length of time that the Engine waits for a reply. If the Engine does not receive a reply within the specified length of time, the neighbor is considered to have failed.

The default is 400 milliseconds.

Multiplier A numeric value from 1 to 20 that used in BFD failure detection. The default is 3.
Passive Mode When selected, the Engine does not send BFD control packets unless it receives at least 1 valid packet from a neighbor.
