CHAPTER 15: IGMP

IGMP

The figure below shows a network running IGMP.

FIGURE 15–1: Advantages of using IGMP

In the above diagram:

•PCs 1 and 4, switch 2, and all of the routers are members of an IP multicast group (the routers operate as queriers).

•Switch 1 ignores IGMP traffic and does not distinguish between IP multicast group members and non-members. Thus, sends large amounts of unwanted multicast traffic to PCs 2 and 3.

•Switch 2 is recognizing IGMP traffic and learns that PC 4 is in the IP multicast group receiving multicast data from the video server (PC X). Switch 2 then sends the multicast data only to PC 4, thus avoiding unwanted multicast traffic on the ports for PCs 5 and 6.

The next figure (below) shows a network running IP multicasting using IGMP without a multicast router. In this case, the IGMP-configured switch runs as a querier. PCs 2, 5, and 6 are members of the same IP multicast group. IGMP is configured on switches 3 and 4.
