Configure HP Procurve switches for mulicast IGMP.

Multicast provides applications with the ability to send a single stream, such as a video transmission, to multiple network hosts at the same time. Multicast is designed to save bandwidth resources on the network and server resources by requiring both to manage only one stream for a group of hosts rather than one stream per host. Most network switches default to broadcasting multicast to all ports, consuming large amounts of resources and defeating the purpose of multicast. Configure IGMP and IGMP Querier on an HP Procurve switch to enable proper management of multicast.
