From this figure, we can conclude that

Which of the following tools cannot be used to match BGP routing entries?

When encountering network failures, engineers often use layered failure handling methods. Because all models follow the same basic premise, when all the low-level structures of the model work normally, its high-level structures can work normally. Please match the following check items with the corresponding level according to the tiered method.
1. Is the TCP connection established correctly?
2. Whether the port opens the interface protocol
3. Whether the Layer 2 addressing is normal, whether the physical status of the interface is UP, and whether the cables and connectors are normal
4. Is the routing protocol working properly?

(Connection question) Please match the command with the realized function.

Please match 0SPFv3LSA with its transmission range.
