A. Generic Network Virtualization Encapsulation

B. Spanning Tree Protocol

C. Equal-Cost Multi-Path Routing

D. Multi-Chassis Aggregation

B. Programmatically migrate layer-3 access from aggregate to access switches

C. Programmatically control physical core network topologies

D. Programmatically provision physical network segments and services
