A. On the RTC, the following configuration is adopted, only the routes of the 2222/32 cinder segment can be filtered out when routing is introduced, IRTClip ip-prefix 10 index 1 deny2000 8 less-equal 32

B. The following configuration can filter out the routes of the 2/32 CIDR block of the white RTD when RTC introduces OSPF routes.

C. RTB learns that the routing next hop for the 2/32 network segment is RTA

D. Adjusting the ISIS priority to 160 on the RTB avoids suboptimal routing problems in the network.

C. By default, matching is made from smallest to largest according to the Rule-ID.

D. By default, matching is based on the principle of "depth first"
