I'm making some small step progress from time to time.
IPTV is working, when I put everything on static, but the IPTV-Packets are flooding the entire Network (as espected). A second problem is, that the IGMP-Leave-Message doesn't come through so the IPTV-Stream is continuing for about 5 minutes.
I'm facing a major technical issue with my central switch (sg-200-26) at the moment:
A Network engineer recommended to re-enable IGMP-Snooping again to avoid the flooding, but after enabling, the switch crashes and reboots after receiving an IGMP. The switch crashes and reboots nearly every 2 minutes and kills the entire company network. The issue is happening with Firmware .58 and .62.
My current attempt is to solve the problem with an extra IPTV-VLAN. I set up a port based vlan (untagged) between microtik eth5 and port 7 and 10 of my central switch. I put all multicast forwarding on static for this vlan and iptv worked propery, but i'm not able to forward the steam to the next switches because I'd have to put extra cables for the extra uplinks.
The next step to the solution will be a tagged vlan for IPTV. I'm going to try to force my mikrotik to tag all incoming IPTV with vlan 8.
the crashing problem was fixed by a factory reset.
the IPTV problem was solved by IGMP-Snooping. The source of the issue was a fritzbox-router connected to my core switch which is used as WLAN Accesspoint. The IGMP-Snooping recognized it as a multicast router and sent his igmp traffic to the fritzbox. The Fritzbox also made the switches to work in IGMPv3 which isn't supported by the mikrotik.
