Does CloudOS7.0 still support classic networks?

CloudOS 7.0 no longer provides the "classic network" design available in CloudOS 5.0; all networks are managed uniformly via VPC networks. However, regardless of SDN or non-SDN networks, the VPC feature allows users to configure arbitrary address segments. To support the function of publishing service addresses through routing as implemented in classic networks, CloudOS 7.0 deploys independent Border devices in the "Layer 3 Unicast Egress" mode.
