B.Packets are distributed across the ports in the channel based on both the source and destination IP addresses.
C.Packets are balanced across the ports in the channel based first on the source MAC address， then on the destination MAC address， then on the IP address.

You work as a network engineer for. You study the exhibit carefully. Based on the output of the show command，
what can you determine regarding EIGRP routing being performed by the switch？ （）
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.
