The Workload asks for Network Configuration Independent of Virtual Machine Controller communication All type of Virtual-Switches supported
Based on learned VLAN configuration get pulled, instantiated and applied to the Network
Facilitates VM Mobility
The Virtual-Machine triggers Network Configuration

Any Subnet anywhere => Any Leaf can instantiate ANY Subnet All Leafs share gateway IP and MAC for a Subnet ARPs are terminated on Leafs, No Flooding beyond Leaf
Facilitates VM Mobility, workload distribution, arbitrary clustering
Seamless Layer-2 or Layer-3 communication between physical hosts and virtual machines
The Network Follows the Virtual-Machine
