Perform an IGMP Join/Leave from the multicast client.
Access the multicast client with issue (usually the set-top box of an IPTV), and start
changing IPTV from one channel to the channel with the multicast issue (if any).
Every time a channel changes, the set-top box sends an IGMP Join for the new
channel as well an IGMP Leave for the old channel.
Figure 7 !
* Figure shows what occurs when a channel is changed through an IPTV’s
point of view.
After performing an IGMP Join/Leave, proceed to step 5.
Did the Zyxel switch receive the IGMP Join/Leave from the
multicast client?
After you perform the IGMP join/leave, the multicast address should appear in the
multicast table. The appearance of the multicast address indicates that the switch
can successfully receive the IGMP join/leave. For the case of MVR, the multicast
group address must have VID in the Multicast VLAN ID.
