As shown in the following figure, the BFD for OSPF network is as follows: 1. OSPF is running between the three devices: FW_A, FW_B, and FW_C. The neighbors are in the FULL state. The association between BFD and OSPF is complete. BFD is complete. To establish a BFD session, the following instructions are correct?

A.

When link a fails, BFD first senses, and FWA and FWB will converge immediately.

B.

link switching is switched in seconds

C.

FWA processes the neighbor Down event and recalculates the route. The new route is link b.

D.

When link a finds a fault, OSPF automatically converges and notifies BFD.
