Abstract: Connecting the External Customer Network to the Ensemble by attaching to ports in the zBX Top-of-Rack (TOR) switch is simple to do, but it is not the same as connecting any external device to just any Layer 2 switch. The connection must be a ROUTED connection and not a SWITCHED connection. The biggest mistake you can make is to attempt a connection that relies on Layer 2 switching protocols. Such attempts will fail and in some cases will cause ramifications for the rest of your external network. This document provides the rationale behind the need for Routed connections and it also supplies some valid external router configurations for successful connectivity to the TOR.
