Table 1 lists configuration options that are often discussed during design conversations. ![]() This document uses EPGs mainly as part of explanation, but contract related features and behaviors shall be applicable to both EPGs and ESGs unless otherwise indicated. It discusses how contracts work, and design considerations and deployment options regarding contracts. The document covers features up to Cisco ACI Release 6.0.
