down. In which two ways will the routers in this network respond to this change? (Choose two.)

A. All routers will reference their topology database to determine if any backup routes to the 192.168.1.0 network

are known.

B. Routers R2 and R3 mark the route as inaccessible and will not accept any further routing updates from R1 until

their hold-down timers expire.

C. Because of the split-horizon rule, router R2 will be prevented from sending erroneous information to R1 about

connectivity to the 192.168.1.0 network.

TestInside 640-801

D. When router R2 learns from R1 that the link to the 192.168.1.0 network has been lost, R2 will respond by

sending a route back to R1 with an infinite metric to the 192.168.1.0 network.

at an increased rate until the network again converges.
