after over a year, I was absolutely happy to see the new SwOS Version 2.10 with a lot of IGMP related improvements, finally it might be possible to use the switch together with "magentaTV" from 'Deutsche Telekom' (aka. T-Online) which requires absolutely IGMPv3 capable switches to work...:
But.... no.... Mikrotik does not get it again........
*) do not ignore RSTP port state when forwarding DHCP, PPPoE or IGMP snooped packets;
*) IGMP snooping: send out IGMPv3 queries by default;
*) IGMP snooping: handle IGMPv3 leaves much better;
I got a rather large home network with a couple of vlans, so I seprated the T-Online Magenta IGMP-'hell' in its own VLAN let the untagging be done by the switches.
So I got the following infrastructure
Dell Poweconnect 7024
Dell Powerconnect 6224
several OpenWRT based Atheros/Broadcom devices as accesspoints (Linksys WRT32X, TP-Link Archer C7)
plus a couple of Netgear GS108E for 'behind the TV'
and..... my Mikrotik CSS 326-24G2S for my Lab.... which is currently (again) freed from my vlan 30 to not interfere with the IGMP-hell.....
Dear Mikrotik Engineers: What is so problematic about the correct, working implementation of IGMP? Yes I know, I hate the protocol maybe as much as you do, because it is not really good from any point of view - but since IPTV is finally arriving and with gigabit internet connections it makes finally a bit sense....
Why works a 25 € Netgear GS108E from a flash-sale on Amazon works way better than my 150 € Mikrotik "professional" Switch?
Sorry for the rant here.... but I bought the Mikrotik device when it came out, because I was convinced, because I was working a long time with Mikrotik Wireless devices and routers, and the only downside of my Mikrotik RB260GS was the lack of IGMP support.... I thought the CSS 326 would be absolutely ideal for me - but it wasn't, it isn't and I doubt it will ever be
I am thinking about buying the CRS305-1G-4S+IN - to use it as a 10 GB ethernet core-switch - but - currently IGMP related I think it acts absolutely as the CSS326 is acting, making my IPTV based on IGMPv3 unusable....
So, please, explain to me, what is the problem and how can *I* help to help you fix it? Is there anything I can do? Maybe a pcap dump with timestamps what happens?
Would be awfully nice of you to make it finally a 'good' switch....
