The most common use of VXLAN is for creating virtual networks over existing physical and logical network infrastructure when deploying a software-defined datacenter.
 
 

Configuring a Trunk Port on ROS installed on top of VMWare Workstation – MikroTik

With VXLAN, virtual machines VMs running in VMware vSphere can connect to the needed logical network and communicate with each other even if they are located on different ESXi hosts in different clusters or even in different datacenters.

VXLAN logical networks are abstracted from the underlying physical networks, and VMs are abstracted from the underlying hardware. Many modern datacenters including datacenters that have virtualization servers use the leaf-spine network topology and the top-of-rack ToR connection scheme. When VMs use a physical network, even with virtual network VLAN isolation of network segments on the second layer, the ToR switches to which rack servers are connected must operate with MAC addresses of physical network devices and VM network adapters to provide the L2 connectivity instead of learning one MAC address per link.

MAC address tables become too large, which causes switch overload and significantly higher capacity demands of MAC address tables compared to non-virtualized environments. When table overflow happens, a switch cannot learn new MAC addresses, and network issues occur. These days, is not enough for large cloud service providers.

Configuration of physical network equipment is performed for network segmentation. Why is UDP used? L3 networks are convenient for administration, and, as we mentioned earlier, the L3 network is the underlay network for the VXLAN network which is the overlay network.

There is a Protocol field in the IP header see image below used to define the data of the higher layer protocol see the table with the OSI model above that is packaged into the current IP packet. You may be thinking: TCP is more reliable. TCP has a mechanism for checking whether data was received and transmitted successfully without loss. If the data was lost, the data is sent again.

If data is lost due to connection issues, this data is never resent. If we would use TCP over TCP, and packets are lost in the underlay session, they are also lost in the overlay session.

Packet retransmit is initiated in the underlay and overlay TCP sessions, which causes network performance degradation. If clients use VLAN tagging, 4 bytes must be added, and the result is 54 bytes.

It is recommended that you increase the frame size when using virtual VXLAN networks in a real network. VMware recommends that you set MTU to bytes or more on distributed virtual switches. MTU points to the maximum size of a payload encapsulated into the Ethernet frame the IP packet size, which has a default value of bytes when Jumbo frames are not used.

The ESXi hosts are connected to different subnets of the physical network. VXLAN overlay networks support unicast, broadcast, and multicast communication modes in the network. In multicast mode, remote VTEPs can be found automatically without the need to manually define all neighbors. Using a standard vSwitch is not recommended. Examples of non-VXLAN hosts are an internet router, a physical server connected to a physical network, etc. NSX Manager is a virtual appliance used to configure and manage VMware NSX components including controllers, edge services gateways, and logical switches.

NSX Manager provides a graphical user interface a web interface for a better user experience. In Workstation, edit the settings for the virtual machine which you want to isolate. In the Hardware tab, click Network Adapter and in the right pane, you must select Custom: Specific Virtual Network and from the dropdown menu, select the vmnet adapter that is mapped to the secondary network card.

In our example, it is vmnet2. The virtual machines are now on the same VLAN. Understanding networking types in hosted products Source: KB Article: You could also use a feature available with teams called Team Segments and use isolated networks segments for testing and running VMs in isolated environments too.

You can see more about Teams and Workstation in my articles below:. A team LAN segment is undetectable and inaccessible from any other network. Connect on: Facebook. Feel free to network via Twitter vladan. This might have been helpful if it had anything whatsoever to do with VLANs instead of just creating a second bridged vmnet.

When VMs use a physical network, even with virtual network VLAN isolation of network segments on the second layer, the ToR switches to which rack servers are connected must operate with MAC addresses of physical network devices and VM network adapters to provide the L2 connectivity instead of learning one MAC address per link. NSX Controller , called a central control plane, is a distributed state management system to control overlay transport tunnels and virtual networks, providing routing and logical switching capabilities. The most common use of VXLAN is for creating virtual networks over existing physical and logical network infrastructure when deploying a software-defined datacenter. VMware recommends that you set MTU to bytes or more on distributed virtual switches. MSP clients can then back up their data securely without impacting other clients. With VXLAN, virtual machines VMs running in VMware vSphere can connect to the needed logical network and communicate with each other even if they are located on different ESXi hosts in different clusters or even in different datacenters. It is recommended that you increase the frame size when using virtual VXLAN networks in a real network.
