Which of the following are characteristics of distributed VXLAN gateways?
- A. A leaf node can function as both a Layer 2 VXLAN gateway and a Layer 3 VXLAN gateway, supporting flexible deployment.
- B. Forwarding paths are not optimal. Inter-subnet Layer 3 traffic between devices connected to the same gateway in a data center must be transmitted to a unified Layer 3 gateway for forwarding.
- C. A distributed VXLAN gateway (leaf node) only needs to learn the ARP entries of servers connected to it, whereas a centralized Layer 3 VXLAN gateway needs to learn the ARP entries of all servers on a network. Therefore, the number of ARP entries supported is no longer a bottleneck on distributed VXLAN gateways, and the network scalability is improved.
- D. The number of ARP entries supported is a bottleneck. A single Layer 3 gateway is used. For tenants whose traffic is forwarded by the Layer 3 gateway, ARP entries must be generated for the tenants on the Layer 3 gateway, but only a limited number of ARP entries are allowed by the Layer 3 gateway, which impedes data center network expansion.
