IGMP/MLD proxies offer the possibility option to combine local multicast networks with a larger multicast infrastructure. In contrast to multicast routers, proxies are lightweight and do not require the support of a multicast routing protocol such as PIM or DVMRP. A common use case is a local stub networks that interconnects with a remote multicast routing domain, e.g. via a tunnel. But it can also be used in PMIPv6 domain to enable multicast for sources and listeners (RFC 6224). The Mcproxy meets the requirements of the IGMP/MLD proxying standard (RFC 4605) and has additional functionalities. The multicast proxy can be instantiated multiple times, is dynamically configurable at runtime, supports multiple upstreams and peering-interfaces for a non hierarchical interconnection of multicast proxies.
