This document describes the way of supporting multiple upstream interfaces for an IGMP/MLD proxy device. The proposed extension enables an IGMP/MLD proxy device to receive multicast sessions/ channels through the different upstream interfaces. The upstream interface is selected based on the subscriber address prefixes, channel/session IDs, and interface priority values. A mechanism for upstream interface takeover that enables to switch from an inactive upstream interface to an active upstream interface is also described.
