Q131. (Topic 3)
The following statement on the RIP network size is correct
A. RIP is based on Bellman-Ford algorithm can correctly calculate the shortest path to large-scale network
B. RIP 16-jump limit is to prevent routing loops in the network resulting in infinite packet transmission
C. Even within the 16 hop limit, for more complex network topology, it is recommended that you do not select the choice of RIP and other routing protocols OSPF
D. only fit in a small network running is a major cause RIP to periodically broadcast their full routing information, routing within large networks are more items of information, which take up too much network bandwidth caused by RIP
Answer: B,C,D
