4.6.4 IGMP

IGMP is a standard defined in RFC1112 for IGMPv1, and in RFC2236 for IGMPv2. IGMP specifies how a host can register a
router in order to receive specific multicast traffic. Configure the switch to use IGMP snooping in subnets that receive IGMP
queries from either IGMP or the IGMP snooping querier. IGMP snooping constrains multicast traffic at Layer 2 by configuring
Layer 2 LAN ports dynamically to forward multicast traffic only to those ports that want to receive it.
