@fio_fan,

Hello! The answer to your question depends on your needs. What you have to know about VXLAN:

  • Adopted for environments with a high number of virtual machines connected to a network. 
  • Works on top of the L3 network.
  • Allows you to build a virtual L2 network over an L3 physical network with an encapsulation technique called MAC-in-UDP. 
  • Has numerous advantages compared to traditional VLAN. However, VXLAN is much more complicated.

As for the main advantages, consider the following:

VXLAN pros

  • Highly scalable networks. Multiple L2 domains can be stretched between various data centers.
  • Supports multi-tenancy, multicast and network segmentation.
  • Flexibility. There is no need for STP. L3 networks work as the underlying network.
  • You avoid overload of physical networks on the L2. 
  • You get centralized network management. 

As for the VXLAN downsides:

  • Initial configuration and deployment are complex.
  • Scaling a centralized controller to manage overlay networks is difficult.
  • You get the headers overhead because of encapsulation techniques.
  • The underlay network requires support for multicast broadcast, unknown unicast and multicast (BUM) traffic.

Let me know if you have any additional questions.
