Important Considerations

The system determines which ports in a VLAN lead to multicast routers by snooping on advertisements from the following routing protocols: Distance-Vector Multicast Routing Protocol (DVMRP), Multicast Open Shortest Path First (MOSPF), and Protocol Independent Multicast (PIM).

Router port entries age out after 100 seconds. Routing protocol advertisements are usually sent every few seconds.

For the CoreBuilder 3500 system and CoreBuilder 9000 Layer 3 modules, IGMP commands exist under the ip multicast igmp menu.
