IGMP/MLD proxies offer the option to easily connect multicast networks to a larger multicast infrastructure. In contrast to multicast routers, proxies are lightweight and do not need to support multicast routing protocols such as PIM or DVMRP. An usage example is in the PMIPv6 domains to provide transparent multicast services for mobile nodes. The mcproxy meets the requirements of an IGMP/MLD proxy and provides additional features. So the multicast proxy can be instantiated multiple times and is dynamically configurable.
