I have the same problem. IGMP proxy leaves a group on all interfaces, not only on the one that got the fast leave message.
I can confirm that. Igmp proxy stops to forward multicast traffic after upstream interface goes down/up. RB2011, ROS 6.16. Upstream inteface on RB2011 is on port 1...IGMP proxy is still broken!
yes, i have the same problem as ropeba. I tested 6.16 version and the bug still persists...Do you also have similar setup with PPPoE server on that router?
6.10 have same problem. IGMP proxy not work after upstream interface link down/link up. Only reboot help.please latest version available for IGMP-proxy, that is 6.10 or even 6.11rc1 if possible.
