About this issue, I did use an AP router as a PPPoE client to get access to the Ros, but when it send an IGMP report to ROS, the ROS didn't send the IPTV traffic to AP. If I change the AP to be DHCP client, then the traffic can be received in the AP.
The ROS setting is the same as the former picture.
Would you please help to find the root cause and give me some advice?
thanks a lot!
