The purpose of this document is to define the requirements for a MLD (for IPv6) or IGMP (for IPv4) proxy with multiple interfaces covering a variety of applicability scenarios. The referred scenarios, while describing not sophisticated service situations, present cases that existing technology does not allow to solve in a simplistic manner. This document is then intended to serve as input for future documents defining the support of multiple upstream interfaces by IGMP/MLD proxies being compliant with the aforementioned requirements.
