For greenfield deployments or deployments with existing Nexus line devices, users can use leverage ACI.

But what about deployments with legacy devices (spanning across L2-L7) from cross vendors. When such an infrastructure is plugged alongside leaf and spine with ACI, how can APIC push down policies to those legacy devices which dont speak openflex or any variant of openflow.

How can we prevent them to turn out as blind spots in the network from APIC management perspective ?
