IGMP Proxy over PPPOE on R200/201

Products Residential Wi-Fi

Hi,
after making lab test for deploy a multicast service on our network, we discover probably a bug on R200/R201 firmware. The IGMP Proxy not working if you have enabled as WAN service PPPoE method. In particular the PPPoE go down and the WAN service became unresponsive. Obviously the IGMP Proxy not working.

Extract of Syslog:

For restore the PPPoE function we need to reboot the device.

Have you the same problem or make we something wrong?

Please provide below information.

  1. DUT configuration or screen capture  of Web UI WAN network configuration.
  2. Multicast service Network  topology details.

We deploy with IGMPv2 to subscribers and PIM-SM(Mikrotik) for our backbone.

I did not see “PPPoE goes down” issue  with IGMP proxy enable in our setup. We can see this type of issue if LCP Echo-Request and Echo-Reply messages are drop by the back end network  due to traffic congestion or packet loss.

Please provide your  network topology diagram.

I have attached Setup diagram.
