In the OSPFv3 network shown in the figure, OSPFv3 is enabled on the interconnected ports of R1, R2, and R3, and all are configured with IPv6 global unicast addresses. Then R1, R2, and R3 will all generate Intra-Area-Prefix-LSA.

Drag and Drop Question
When configuring port security on a switch, the administrator also enables static MAC address flapping detection. If static MAC address flapping occurs, the switch takes the configured action to protect the interface.
Match the names of interface security protection actions with corresponding operations.

As shown in the figure, an engineer uses 4 routers to test branch network interoperability. Among them, R1, R2, and R3 in branch 1 deploy OSPF to achieve network interoperability. R2, R3, and R4 in branch 2 deploy IS-S to achieve network interoperability.

Now the engineer wants to realize the loopback address of R1 to R4. Which of the following operations can meet this requirement?

In a campus network using Eth-Trunk with dynamic LACP mode, traffic across bundled interfaces is unevenly distributed. Which factor determines how traffic is load-balanced?

Which of the following commands can be configured on an IS-IS Level-1-2 device to prevent the Level-1 device from generating a default route?
