In a prior blog, Creating Logical Networks and Services with VMware NSX on Dell Infrastructure, I discussed how easily VMs can be moved from physical (VLANs) to logical networks (Network Virtualization Overlays or NVOs). In practicality, there will almost always be some physical resources on a network that are not virtualized or remain on the physical network (VLANs). So how can VMs on a logical network communicate with resources on the physical network?
One method of communication can be done with the VMware NSX L3 Edge Services Router. However, if you want to just bridge between the logical and physical entities such as bridging between VXLAN to VLAN, the VMware NSX L2 Gateway can be used and this specific use case is discussed in more detail in this blog.
