VXLAN allows a virtual network to provide access services to a large number of tenants. In addition, tenants are able to plan their own virtual networks, not limited by the physical network IP addresses or broadcast domains. This greatly simplifies network management.
When VXLAN in centralized gateway mode for static tunnel establishment is deployed, traffic across network segments is forwarded through Layer 3 VXLAN gateways to implement centralized traffic management.
IPv6 VXLAN can be deployed in centralized gateway mode so that all inter-subnet traffic is forwarded through Layer 3 gateways, thereby implementing centralized traffic management.
When VXLAN in centralized gateway mode using BGP EVPN is deployed, traffic across network segments is forwarded through Layer 3 VXLAN gateways to implement centralized traffic management.
IPv6 VXLAN can be deployed in centralized gateway mode so that all inter-subnet traffic is forwarded through Layer 3 gateways, thereby implementing centralized traffic management.
Distributed VXLAN gateways can be configured to address problems that occur in centralized gateway networking. Such problems include sub-optimal forwarding paths and bottlenecks on Layer 3 gateways in terms of ARP or ND entry specifications.

In the scenario where a data center is interconnected with an enterprise site, a CE is dual-homed to a VXLAN network. In this way, carriers can enhance VXLAN access reliability to improve the stability of user services so that rapid convergence can be implemented in case of a fault.

In scenarios where an IPv6-based data center is interconnected with an enterprise site, a CE can be dual-homed to an IPv6 VXLAN to implement rapid convergence if a fault occurs, thereby enhancing access reliability and improving service stability.
In the Network Function Virtualization Infrastructure (NFVI) telco cloud solution, the NFVI distributed gateway function enables UE traffic to pass through the data center network (DCN) and be processed by the virtualized unified gateway (vUGW) and virtual multiservice engine (vMSE). In addition, traffic can be balanced during internal transmission over the DCN.
In the Network Function Virtualization Infrastructure (NFVI) telco cloud solution, the NFVI distributed gateway function enables mobile phone traffic to traverse the DCN in load-balancing mode and to be processed by the virtualized unified gateway (vUGW) and virtual multiservice engine (vMSE) on the DCN.
This section describes the typical application scenarios of VXLANs, including networking requirements, configuration roadmap, and data preparation, and provides related configuration files.
