FANTATIC VIDEO! Thank you! You’ve just answered so many questions I had on the topic. I have over 150 APs, 50 switches and more than 900 wireless clients during any given day. We have DANTE audio traffic, video surveillance traffic, chrome casts, Apple TVs, wirelessly connected interactive flat panels and over 55 printers and copiers all trying to be seen on the network via Bonjour / AirPrint. Although I have IGMP turned on throughout the network, and block broadcast traffic from LAN to WAN, I couldn’t understand why sometimes the DANTE devices and my AirPrint enabled printers and copiers would appear for a set period of time, and then disappear. I’ll be looking at how to implement an IGMP querier first thing in the morning! Thank you!
I really enjoy what you are doing, it would me great if all such type of videos had simple scheme with all device and connections between them, so when you add some new device, we see simple scheme, where it was attached/connected. It would be easy to follow and understand what you are trying to achieve/show, especially for people like me - non native English speakers. Thanks.
Great demo! Thank you. Just wondering... Does this mean that the managed switch needs an ip-address on every IGMP-enabled VLAN to be able to send IGMP Membership Queries (192.168.0.250 in your demo @12:45)?
@@TallPaulTech Haha, well okay then. I need to setup a bodycam solution on an ad-hoc/MANET network with body-worn radios for first responders. Multicast is key to keep the bandwidth to a minimum. The radios can handle voice and data (flatout OSI 2) and support IGMP. Your video helped me in understanding then protocol. Thanks Paul!
That half sounds interesting, and half sounds over complicated. Who's wearing this radio? Like firefighters or something? Are you talking about a Wi-Fi mesh link between them to put multicast over? If so, you're going to have to consider a lot of things and be careful how you do it.
@@TallPaulTech LEO CRC units. The radios are milspec and have provisions and custom protocols to account for the problems associated with wireless multicast transmissions. It is not 802.11 but proprietary waveforms in a MANET configuration and indeed are mesh operated. It is not a new concept per se, but to me it is. Diving deep in your multicast videos helped me understand the fundamentals, so it will help me in implementing. It will be a fun project but indeed, a dynamic environment where this will be used might propose some challenges. I have a private playlist link on youtube to videos of the radios I could sent you.
Should I be actively setting up igmp so my Roku and chromecast run more efficiently? They use ssdp, upnp and Mdns protocols which are both broadcast/multicast.
Great video. Quick question. When running Unifi kit only 2 options exist (running UDMP), enable IGMPv3 (at the individual WLAN level) enhancements and IGMP snooping (at the LAN level). Do you advocate having both of these enabled period or are there situations where 1 both should be disabled etc ? Thanks
Perfectly explained. I have a TL-SG3424 TPLINK switch that has no "Querier State" function and the stream does not leave the client in port 5 by the client leaving port 8. Why? I also have switches that have the "Querier State" function and I also do not have to turn them on on some switches, and on some I need D-LINK DGS 1210-20. Why?
Hey, got a question for you, I'm tweaking my network settings. I have a Chromecast, several other streaming players, and several smart speakers plus smart bubs. My router supports IGMP v2, and 3, and also offers options to enable / disable snooping, and proxy. From my research proxy is for multiple network access. Since I'm only dealing with one network and one subnet, if I understand correctly, IGMP proxy is not needed here, but snooping could help with the streaming data so it doesn't flood devices that don't want it. Is this correct, or should I enable both. Thanks. There isn't a lot of good info on IGMP regarding my setup, and what I want to do, so that's why I'm asking around for clarification. Thanks
Great. I was wondering what IGMP is good for now that it was advertised in the switch to be configured. I just do not understand why is IGMP off at delivery of a new switch. ?
Love your videos! Do you think you could do one on your Chanalyzer setup, what RF antennas or external USB equipment (Wy-Spy?) you are using and what someone would need to troubleshoot RF issues or just help "prove it's not the network"? Keep up the great work!
Hello, very good, I have a doubt, the igmp snooping is recommended to deactivate it to play for example on a PlayStation 4 or is it better to leave it activated? Thanks in advance and best regards
hey great video just want to asking about this , i had a problem when running a couple of multicast above 20 and some random channel will get no signal message in tv. note we have turned on the igmp and the igmp querrier ( the switch is aruba ). thank you
Hey mate, I see you're a long time subscriber. I may be back in the near future. I'm just looking for a reason to make videos anymore, but I can't resist the urge. It's just a bit of effort for something where the majority of the world just wants to watch stupid shit on youtube, or have it flooded with corporate video. If you give me some ideas of the type of content you'd like to see, then I'll see what I can do.
You have covered a lot of topics, very informative. Thank you. Only thing I can offer is a lot of people are using public wifi at the moment, is the any way to check the connection is good and not monitored on Linux laptop or phone .I know a vpn
Hey hey, I need my fix of cat caging, roast making, rude network diagram innuendos. Hope everything is okay. Did a garage shelving unit fall on you and you cant get out from under it? Also, just noticed the "Jesus loves you but I think you're a c#*t" picture on the shelf. - Well played.

Sounds like you need me on the job on your network
Awesome to be able to see how IGMP works in real time. Clearest explanation I've seen, great video!
I always couldn't understand multicasts and igmp - this video made me much less scared of it! Thanks.
i think exactly the same. Thanks the video.
Been running IPTV multicast for years, your detailed video opened my eyes... Great videos!
One of the best explanations of IGMP I’ve seen. Thank you 🙏
Thank you sir! This is the best info on the internet on how igmp works
👍
Yes! Thankyou
Thumbs Up !! This is the best video for IGMP !!
Best explanation and demonstration I found on TH-cam
Great explanation of IGMP. Up to the point and great presentation.
Nice demonstration setup and awesome explanation. Thanks for uploading!

You have no idea on how helpful ur videos are. greetings from brazil mate.
Thanks mate. How's the networks going over there?
Where have you been? Hopefully all is well. Absolutely appreciate you and your content.
Great Demonstration. Hope it would help lot of them out there.
Great demo! I loved it.
What a wonderful demo 🔥
Really amazing and informative content! Thanks!
Very well explanation 👍
Wow...this is awesome representation!!!
This is so good. Great explanation!!
Great demo! Thank you.
Just wondering... Does this mean that the managed switch needs an ip-address on every IGMP-enabled VLAN to be able to send IGMP Membership Queries (192.168.0.250 in your demo @12:45)?
Correct, as that will be the source IP address for the query on that VLAN.
Awesome explanation thanks 🎉🎉
Great demo! Love all your multicast content. I have to implement multicast at work and this helps me a great deal in understanding. Thanks!
Well come on, don't be shy. Tell us what kind of setup you're doing.

thank you! awsome video!
Thank you for your video , very intresting. as I can see , there is no need for L3 switch, L2 can do the same job, am I correct?
wow amazing thank you for the knowledge share.

That's a hell of a question. I can't answer all their possible RF issues in one video! I might think of examples and do some RF stuff in the future.
great job mate

hey great video just want to asking about this , i had a problem
when running a couple of multicast above 20 and some random channel will get no signal message in tv. note we have turned on the igmp and the igmp querrier ( the switch is aruba ).
thank you
Great video..! Thanks..
this is good stuff, thanks!
nice and wonderful 👍
Thanks!
Mate, thanks for that!
This threw me off once, had a big production, they guys tested the stream for less than a minute and said all good, then igmp timed out on the day!
Double Thumbs Up!
Just imagine if this guy were ever to move houses
How did you configure the AP to turn mcast into unicast?
Do ipcam onvif also needs igmp
did you get the van already?
Not yet. Getting more ideas in the meantime though
Really looking forward to more videos, hope you are ok
