Official Moderator Posted January 4, 2022 Share Posted January 4, 2022 @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.
