QUESTION NO: 6
With the development of data centers, a large number of services are deployed on virtual machines (VMs). The original VLAN isolation solution cannot achieve isolation between so many VMs. VXLAN uses VXLAN Network Identifiers (VNIs) to provide a larger range than VLAN IDs, so that a larger number of VMs can be isolated.
