Asante Technologies 3500 Series Configuring IP Multicast Traffic Management, Igmp Snooping

Page 56

Protocol-Independent Multicast (PIM), routers maintain forwarding tables that they use to forward multicast datagrams.

Packets delivered to members of the multicast group are identified by a single multicast group address. Any host, regardless of whether it is a member of a group, can send to a group. However, only the members of a group receive the message. Membership in an IP multicast group is dynamic; hosts can join and leave at any time. There is no restriction on the location or number of members in a multicast group. A host can be a member of more than one multicast group at a time.

IGMP Snooping

A traditional Layer-2 switch is unable to determine which end stations on the LAN are interested in which multicast groups. To avoid unnecessary flooding, the switch may use IGMP Snooping. That means the switch listens to IGMP messages to learn which ports want multicast traffic from which multicast groups. The switch inserts the correct Ethernet multicast address into the forwarding table for the ports where an end station has joined a multicast group.

4.5.1 Configuring IP Multicast Traffic Management

The Multicast Traffic Management Menu allows you to set up group transmission. To access the Multicast Traffic Management Menu, type c in the Configuration Menu. You will see a screen similar to the following:
