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. If load sharing is configured, traffic is evenly distributed across each link
B. For each of the equivalent routes, you can assign a priority, with the highest priority routes preferred and the rest as backup routes
C. 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
D. 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

質問 6：
The OSPF3 protocol is a separately developed protocol that differs somewhat from OSPF2 in that OSPFv3 is link-based rather than network segmented, and the following statement is incorrect?(). Single choice questions).
A. For two OSPF routers connected to the link, you can establish a neighbor relationship even if you do not configure a unicast IPv6 address
B. Two OSPF routers connected to the link can establish a neighbor relationship even if their IPv6 address prefixes are different
C. All OSPFv3 interfaces use the Link-Local address as the destination address of the message
D. The routing information obtained by the OSPFv3 router from the neighbor uses the neighbor's Link-Local address as the next hop in the forwarded packet
正解：C

質問 7：
