When there are multiple redundant links in an IS-IS network, multiple equivalent routes may occur. Regarding equivalent routing within an IS-IS network, which of the following descriptions is wrong?

A. When the number of equivalent routes present in the networking is greater than the number configured by the command, and these routes have the same priority, the next hop device System IlD large routes are preferred for load sharing

B. After you configure the equivalent routing priority, when the IS-S device forwards traffic to the destination segment, it will not use load sharing, but forward the traffic to the next hop with the highest priority

C. For each of the equivalent routes, you can assign a priority, with the highest priority routes preferred and the rest as backup routes

D. If load sharing is configured, traffic is evenly distributed across each link
