MVR enables Layer 2 network installations to deliver bandwidth intensive multicast streams. It is primarily aimed at delivering IPTV over Layer 2 networks, but it is valuable in many existing EAPS (Extreme Automatic Protection Switching) or STP (Spanning Tree Protocol) installations. This section explores a few possible deployment scenarios and configuration details. Of course, real world networks can be lot different from these examples. This section is meant to present some ideas on how to deploy MVR over existing networks, as well as to design new networks that support MVR.
