Layer 3 Multicast Features For information about configuring L3 multicast features, see "Managing IPv4 and IPv6 Multicast" on page 1167. Distance Vector Multicast Routing Protocol Distance Vector Multicast Routing Protocol (DVMRP) exchanges probe packets with all DVMRP-enabled routers, establishing two way neighboring relationships and building a neighbor table. It exchanges report packets and creates a unicast topology table, which is used to build the multicast routing table. This multicast route table is then used to route the multicast packets. Internet Group Management Protocol The Internet Group Management Protocol (IGMP) is used by IPv4 systems (hosts and routers) to report their IP multicast group memberships to any neighboring multicast routers. PowerConnect 8000/8100-series switches perform the "multicast router part" of the IGMP protocol, which means it collects the membership information needed by the active multicast router. IGMP Proxy The IGMP Proxy feature allows the switch to act as a proxy for hosts by sending IGMP host messages on behalf of the hosts that the switch discovered through standard IGMP router interfaces. Protocol Independent Multicast-Dense Mode Protocol Independent Multicast (PIM) is a standard multicast routing protocol that provides scalable inter-domain multicast routing across the Internet, independent of the mechanisms provided by any particular unicast routing protocol. The Protocol Independent Multicast-Dense Mode (PIMDM) protocol uses an existing Unicast routing table and a Join/Prune/Graft mechanism to build a tree. PIM-DM creates source-based shortest-path distribution trees, making use of reverse path forwarding (RPF). 84 Switch Features
