Exhibit：
A.There are 20 neighbors in the EIGRP neigbor table.
B.EIGRP is running normally and receiving IPv4 routing updates.
C.The switch has not established any neighbor relationships. Further network testing and troubleshooting must be performed to determine the cause of the problem.
D.EIGRP status cannot be determined. The command show ip eigrp topology would determine the routing protocol status.
