Which of the following routing protocols could NOT be used with this design?
A. RIPv1
B. RIPv2
C. EIGRP
D. OSPF
Correct Answers: A
Explanation:
The network design displayed has subnets of a major classful network located in opposite directions from the perspective of some of the individual routers. This configuration can be accommodated by any routing protocol that supports Variable Length Subnet masks (VLSM) or the transfer of subnet mask information in routing advertisements.
RIPv1 supports neither of these. RIPv1 will automatically summarize routing advertisements to their classful network (in this case 192.168.1.0/24). This action will cause some of the routers to have routes to the same network with different next hop addresses, which will NOT work.
EIGRP, RIPv2 and OSPF all support VLSM and can be used in the design
