ICMP v3 Problems / IPTV with my new ICMP v3 compatible switches

Hello everyone,

Because I had problems with my old switches and my new IPTV by Swisscom (main boardband provider in switzerland) I bought two new switches which are compatible to ICMP v3 snooping (a ZyXEL GS1910-24 and a ZyXEL GS2200-8).

I configured the two devices like this:
ZyXEL GS2200-8
gs2200-8 icmp config
and the ZyXEL GS1910-24:
gs1910-24 icmp config
But as soon as I turn on the IPTV the whole network goes down within seconds... so I guess I did something wrong. Maybe someone could point me in the right direction.

A little bit more detailed information about my setup:
The internet fiber router is connected to the port1 of the gs2200-8 and the port2 goes to the rj45 patchpanel which is connect to the media room where the cable is patched to the port1 of the gs1910-24 and on the iptv is patched to the port2 of the gs1910-24.

If you need any more informations just let me know.

Thanks and cheers,
Yves

This all did not work...

I had to put the Port1 of the 1910-24 to Routing Mode and the Port2 into Fast Leave Mode. I also had to activate Leave Proxy Enabled and also the Proxy Enabled Option.

Now it works flawless :)

Enable the Querier option on the 2200.

Disable Unknown Multicast Flooding on the 1910.
