A network design shows two routers directly connected to an Ethernet switch using optical connections. There is an OSPF adjacency between the routers. In this design, which solution will ensure that interface down detection is reported as quickly as possible to the IGP?
A) optimized OSPF SPF timers
B) Bidirectional Forwarding Detection
C) automatic protection switching
D) optimized OSPF LSA timers
E) Ethernet OAM CFM monitoring
