Figure 1-4: 6306 IP Multicast Operation
The 6306 IP Multicast Operation works in the following manner:
1. The client issues an IGMP Join Request (Unsolicited report) Layer
2 broadcast.
2. The 6306 modem listens for any IGMP packets (IGMP snooping)
and maintains a table mapping the IP Multicast stream to the port.
3. The 6306 forwards the IGMP Join Request upstream through the
MIU to the IGMP-enabled switch.
