FIGURE 119 – IGMP concepts – Isolating multicast traffic in a network ............................................. 217
FIGURE 120 - In a Layer 2 network, an IGMP multicast traffic goes to all the nodes. In the
figure, T1, a surveillance camera, using multicast, will send the traffic to all the nodes - R1
through R6 - irrespective of whether they want to view the surveillance traffic or not. The
traffic is compounded when additional cameras are added to the network. End result is that
users R1 through R6 see the network as heavily loaded and simple day to day operations
may appear sluggish. ................................................................................................................ 219

IGURE 121 - Using IGMP-L2 on Magnum 6K family of switches, a Layer 2 network can
minimize multicast traffic as shown above. Each switch has the IGMPL2 turned on.
Each switch can exchange the IGMP query message and respond properly. R4 wants to
view surveillance traffic from T1. As shown by (1), a join request is sent by R4. Once the
join report information is exchanged, only R4 receives the video surveillance traffic, as
shown by (2). No other device on the network gets the video surveillance traffic unless they
issue a join request as well. ...................................................................................................... 220
