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.
