I have a software which delivers OS images to notebooks. The software uses multicast to transfer the image.Now the source and clients are connected directly to a Cisco 4506 switch with Supervisor Engine IV.They are all in the same VLAN.Do I need to configure the switch to make the multicast work properly? and How ? A Router is needed or not ?
Re: Constraining multicast traffic in the same vlan
From the document "Constraining Multicast Traffic with Source and Receivers on the Same VLAN on Catalyst Switches", I know that a router is needed in my enviroment. Now,we use the software in real enviroment without a router. It works! From the "show ip igmp groups", we see no multicast groups. From "show interface", we see multicast packets passing through the interface. It really works.
Also, I get a little confused. The 4506 itself is a layer 3 device, why we need another L3 device to make the multicast work ?
