Huawei defines VXLAN (Virtual Extensible LAN) as an overlay virtualization technology that functions similarly to a Layer 2 VPN , enabling the extension of Layer 2 networks across Layer 3 infrastructures.
VXLAN encapsulates Ethernet frames within UDP packets, allowing tenants to build isolated virtual networks over any IP underlay with reachable routing.
The statement is correct because VXLAN enables Layer 2 adjacency across geographically distributed data centers , which is a key requirement in cloud and virtualization environments. It supports large-scale multi- tenant isolation using VNIs (VXLAN Network Identifiers) , significantly exceeding VLAN limitations.
Additionally, VXLAN gateways (either centralized or distributed) play a crucial role. They provide communication:
Within VXLAN networks (intra-subnet and inter-subnet via distributed gateways) Between VXLAN and traditional networks (e.g., bare-metal servers or legacy VLAN-based systems) Huawei CloudFabric solutions heavily rely on VXLAN with BGP EVPN control plane to achieve scalable, automated, and efficient data center networking.
Therefore, the statement is TRUE .
