Which of the following statements about VXLAN is false?

• A.Layer 2 and Layer 3 VXLAN gateways must maintain VBDIF interfaces. Otherwise, users cannot communicate with each other through these interfaces.
• B.A Layer 2 VXLAN gateway forwards traffic to a VXLAN network and can also be used for Intra- subnet communication on the same VXLAN network.
• C.A Layer 3 VXLAN gateway is used for inter-subnet communication on a VXLAN network and communication with external non-VXLAN networks.
• D.A VBDIF interface is a logical interface created based on a BD. It is similar to a VLANIF interface on a traditional network.

In mesh networking, APs have different roles. Drag the AP roles on the left to the role descriptions on the right.

정답:

Explanation:
* MP: Mesh node that uses IEEE 802.11 MAC and PHY protocols for wireless communication. This node supports automatic topology discovery, automatic route discovery, and data packet forwarding. It can provide both mesh service and user access service 1 .
* MPP: MP node that connects a WMN to MPs on other types of networks. This node can function as a portal for communication between internal mesh nodes and external networks 1 .
* Neighbor MP: Neighboring MP with which an MP prepares to establish a mesh link 1 .
* Candidate MP: AP that directly communicates with a mesh node 2 .
