Two routers have established a point-to-point network using PPP. The administrator has configured the routers to run OSPF in the same area with the same router ID, what will behavior will occur as a result of the configuration?

• A.The routers will build a neighbor relationship even though both routers are using the same router ID.
• B.VRP will notify of a router ID conflict between the two routers.
• C.The routers will build an adjacency even though both routers are using the same router ID.
• D.The routers will not send hello packets to each other because they are using the same router ID.

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.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
• C.RIP 16-jump limit is to prevent routing loops in the network resulting in infinite packet transmission
• 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
