Refer to the exhibit. The network shown in the exhibit is running the RIPv2 routing protocol. The
network has converged, and the routers in this network are functioning properly. The
FastEthernet0/0 interface on R1 goes down. In which two ways will the routers in this network
respond to this change? (Choose two.)
A.
R1 will send LSAs to R2 and R3 informing them of this change, and then all routers will send
periodic updates at an increased rate until the network again converges.
B.
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.
C.
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.
D.
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.
E.
All routers will reference their topology database to determine if any backup routes to the
192.168.1.0 network are known.
Explanation:
RIP version 2 will send triggered updates when the topology changes like when a link goes down.
The following are the key characteristics of RIPv2 pertaining to this question:
