This paper was written to help business partners and systems engineers with configuring Rapid Spanning Tree Protocol (RSTP) loop avoidance for converged networks. This configuration can be generalized and applied to most converged networks from various IP PBX vendors in order to provide loop avoidance and prevent end-user cabling errors from taking down voice, video and data application services. Layer 2 loops can occur in converged network environments, sometimes even with Spanning Tree Protocol (STP) enabled. Most loops are accidental, but they can cripple voice and data communication services across entire segments. Spanning tree is disabled on all Extreme Networks switches by default.
