We have a weird permutation where .. if we hook an iptv multicast Set top box off a cable modem .. one works 'fine'. Two .. dont work right. We have a case where if one leaves a channel it dumps it on both STBs. odd part is .. if you put a Cisco 3750E inline.. that solves it. Were looking for insights.. we do see the 3750E sees the multicast querier coming from the CMTS. Ideally we are trying to get this to function with low cost equipment not cisco gear. Looking for some insights to troubleshoot igmp in this case..
Basic network summary, 10GigEs source multicast via PIM to a routed cable mac interface that is pim enabled and igmp capable the other end is a bridge only modem TM3402. Works with 3750E on the modem .. but using built in modem switch does not work properly a dumb switch does not work. we are sourcing a dumb snooping capable switch (netgear) to test further.
