Just brilliant!! Thanks for the video. I envy you because, you broke down a complicated topic that requires several hours of lecture into a 42 minute video and more over you made it crystal clear and fun to listen to. Bravo!
Thank you so much Kevin for this video, it helped me a lot at this moment because I am doing a Multicast lab at work. You can not imagine how much your videos have helped me (CCNP R&S, CCNA and CCNP Collab and youtube videos), I can say I am where I am thanks to my effort and the best "virtual instructor or teacher" who is you, and taking into account that english is not my native language. All I can say is THANK YOU SO MUCH and I have recommended you to all my friends and colleagues. Have a really good day Kevin.
Fantastic. After hours of reading sites and papers on "how to do basic multicasting", I found this. You nailed it. I can walk back to my network, configure it for multicast and understand what I'm doing. Thanks Kevin!
So many videos out there trying to explain the concept of multicast routing by simplifying it to the point it leaves so many unanswered questions. What they fail to understand is that sometimes as a learner you need to go deep to truly understand what is happening. Great video Kevin, you have helped a lot!
Thank you, thank you, thank you, Mr. Wallace! I read several Cisco docs and struggled for weeks to understand how Cisco Multicasting work; however, after watching this vid the lightbulb came on.
Mr. Kevin Wallace. I was trying to understand multicast for about a year now and wasn't getting the concept. it was very frustrating. When I watched this video, the lightbulb just turned on. The basics made sense. Especially understanding auto-rp. Now I know why, it is most beneficial to run Sparse-dense than either sparse or dense modes. THANK YOU SO MUCH. Already subscribed and looking to view more of your videos.
wooahh this video is way back 2016 and I am using this for my encor study.. I understand multicast way better with kevin than reading OCG. Just Fantastic!!!
Great video explaining multicast. IGMPs are used for joinibg multiicast group. Then, the multicast messages to group members are sent in reverse-path-forwarding to avoid duplicate packets. And PIM-DM and PIM-SM are kinda like multicast ROUTING protocols that utilize pruning and grafting to optimize routes.
You're funny and have a natural ability to convey things!! This is the first video I've seen of yours, and you now have a new subscriber!! There's so many others that I just can't click with, but you're doing a fantastic job! Thanks and best wishes
I love this video, I understood everything clearly, your voice doesn't put me to sleep Thank God!!! Thank you so much for this lesson, I really appreciate it.!
I really enjoyed the video. You have an excellent teaching style. I appreciate you taking the time to put together all the visual aids/animations, it really helps!
Really nice quick tutorial for understanding. Forgot the concepts as its not widely used everyday for deployments. But now I recalled the concepts. Thanks Kevin!!!!
i tried to learn Multicast Multiple time, this is the first time I understand it correctly. Simply Brilliant.......... Thank you Sir for the nice video
Always enjoy your vids KW. Keep up the great videos! I used one of your old multicast videos to setup multicast on my network but without the last bit on mapping agents and advertisement availability.
very information in short time, definitely recommend for someone who want to understand the multicast. Kevin we all really appreciate your hard work Thanks and keep making the videos like this. you made it so simple.
big shout out to you kevin, that video helped me a lot. great explained and also a very nice and clear animation, just amazing work, please do more like that.
every day, when i see one of your detailed video, i become more determine to check hands with you in coming event in Vegas. thanks again for informative video. keep it up. Cheers
This Video is awesome and on point.You are the best Kevin.Much love for your videos and master touch explanation. You are a blessing to this generation.
Kevin, thank you so much. Your explanation has been very helpful and clear. I am going to forward it to a couple of friends. Please, continue showing up more and more techniques. Best regards.
Thanks for the good explanation. May I ask you a question? I have a streamer running on my router OS embedded. The stream is coming over the udp to the multicast address. When I route the stream to my internal router interface (where PC is connected) VLC is successfully connecting and playing video. But I need to stream outside and when I rout the stream to the external interface I see the multicast traffic running (with tcpdump), but my VLC on my local PC doesn't connect anymore. My provider told me they had IGMP and PIM set and running. Unfortunately I cant check the stream as I have no other available PC. And the VLC on the smartphone doesn't support udp routing. What I misunderstood? What am I doing wrong?
Thank you Mr. Wallace for this video. Your videos and book helped me pass my Route exam. Hopefully you will produce a full video series on multicast and QoS.
Estimated Kevin. Thank you a million for your videos, they are a invaluable contribution to the newtworking audience. Appreciate it!. Best regards from the Plurinational State of Bolivia.
Thanks for always making what looks like the most complex topics look like a piece of cake. Is there a Holy Kevin Grail where we can go pay homage?...lol, but on a serious note, there should be one!
Thanks Mr Wallace. Greetings from India. Very clearly Explained. I have your CCNP Video nugget since many years which I use for revising very frequently Its great too. & Is there any way we can find people who dislike such Useful Videos. :-)
Kevin you are truly Awesome!!!... Absolutely excellent explanation of the fundamentals & more...Great Job...and a big big Thank you for the knowledge shared by you...God Bless You
Great video illustrating multicast. Quick question, what if I wish to configure different RPs for different multicast groups? How does a mapping agent decide who wins the elect of RPs?
great video, by the way I wanna ask about the Flag A in the Outgoing interface List in 34:18, cause i'am confused as assert mechanism is only actif on multi-access networks contrary to the topology presented in the video
Thanks alot for the video Kevin, your presentation is really good and simple to understand Can you please update the videos related to anycast in depth from start to finish that will be really good thank you ☺️
Hello Kevin, thank you for brilliant video. I was struggling understanding Distribution Tree concept until seeing your video. By the way, do you have video on PIMv6 ?
Kevin, Thank you for the usual great presentation. I have a question; why is it that in PIM Sparse mode, when a request was made by the receiver through R3 to the RP, to request Multicast traffic; why did R1 send the traffic to both RP and R3. Shouldn't R1 only send the traffic to the RP, given that R1 is also configured with the IP address of RP? I am thinking, this would have avoided the extra messaging from R3 to both source and the RP.
Thanks Kevin for the quick response; it was my oversight. I went and viewed the video again, and realized that initially, R3 was only getting traffic from just R2 (RP); not from both R1 and R2. Thanks again for the great videos.
Am I the only one that noticed the mistake on the interface used for R3 in the topology? in the draw I see that R3 has three interfaces Fa 0/0, Fa 2/0, and Fa 1/0, in the configuration demo, I kept getting lost because there is continuously used Fa 0/1 on R3 @Kevin can you confirm this is the case? there is a mistake in the labeling of the R3 interface connected to R2?
Just brilliant!! Thanks for the video.
I envy you because, you broke down a complicated topic that requires several hours of lecture into a 42 minute video and more over you made it crystal clear and fun to listen to. Bravo!
Thanks a ton Sree! I'm so glad the video was helpful to you.
You just saved me from reading 60 pages of multicast material. Your explanation is clear and concise !
This video is pure gold for someone wanting a crash course in multicast routing. THANK YOU.
You're very welcome! I'm so glad you enjoyed the training.

I"M so glad that you took the topic of multi-casting and broke down into smaller easier to understand pieces.
Its amazing how he taught everything in a single video
Thank you, thank you, thank you, Mr. Wallace! I read several Cisco docs and struggled for weeks to understand how Cisco Multicasting work; however, after watching this vid the lightbulb came on.

MULTICAST FOR MY CCNP ENCOR HAS BEEN SIMPLIFIED THANKS KEVIN WALLACE
Thanks for this video, I already purchased your ENCOR and ENARSI courses on Udemy and am thoroughly enjoying them!
I love this video, I understood everything clearly, your voice doesn't put me to sleep Thank God!!! Thank you so much for this lesson, I really appreciate it.!
Kevin will never put you to sleep. Unlike many in this game, he actually has a personality XD
I really enjoyed the video. You have an excellent teaching style. I appreciate you taking the time to put together all the visual aids/animations, it really helps!
Thanks very much! I'm so glad you enjoyed the training.
Am waiting for your CCIE R&S. First time I have fully grasped multicasting
"Show IP MRoute" to show the multicast routing table. I would give you 5 thumbs up if I could. Learned so many new things in the video!
One of the best videos that you ever made, Kevin!
Many hours concluded in just 42 minutes.
Thanks a lot.
Really nice quick tutorial for understanding. Forgot the concepts as its not widely used everyday for deployments. But now I recalled the concepts. Thanks Kevin!!!!
i tried to learn Multicast Multiple time, this is the first time I understand it correctly. Simply Brilliant.......... Thank you Sir for the nice video
Thanks for this video. This is a subject I was not grasping until I saw this video. Now I have the foundation to dig deeper!
that was ovewhelmingly clear. i couldnt wrap my head around multicasting by reading the ocg. thanks!
I like the way you clarify the concepts easily.
preparing for CCNP DC for multicasting this is what i needed. all conecpt get clear. Thank you @kevin
Always enjoy your vids KW. Keep up the great videos! I used one of your old multicast videos to setup multicast on my network but without the last bit on mapping agents and advertisement availability.

Hi Kevin, I hope you're doing well.
At 22:26, doesn't R2 send the Graft message to both R1 and R3?
big shout out to you kevin, that video helped me a lot. great explained and also a very nice and clear animation, just amazing work, please do more like that.
every day, when i see one of your detailed video, i become more determine to check hands with you in coming event in Vegas.
thanks again for informative video. keep it up. Cheers
Great job Kevin, your teaching style is very engaging and makes it clear and easy to learn! Keep up the good work!
Thank you Mr. Wallace! A difficult topic explained clearly and concisely. You really have a knack for making things easier to understand:)
You are a god. This is a jewel for multicast beginners like myself. Much appreciated.
Hi Kevin, I'm a student and just wanted to say thanks for the video! Great stuff.
This Video is awesome and on point.You are the best Kevin.Much love for your videos and master touch explanation. You are a blessing to this generation.
Kevin, thank you so much. Your explanation has been very helpful and clear. I am going to forward it to a couple of friends. Please, continue showing up more and more techniques. Best regards.
Thank you for the video. I am learning it for the SP track, but I need to know the basics!
Great style of teaching with lot of clarity, so all levels of listener's understand 👍
Hi Kevin, I enjoyed the video. Very concise. Also noticed a minor typo on the network diagram at 29:22. Interface on R3 to R2 should be 0/1 not 1/0.
Noticed the same thing. Thx✨
❤your analogies are on point, Kevin 😮
Thanks for the good explanation.
May I ask you a question?
I have a streamer running on my router OS embedded. The stream is coming over the udp to the multicast address.
When I route the stream to my internal router interface (where PC is connected) VLC is successfully connecting and playing video.
But I need to stream outside and when I rout the stream to the external interface I see the multicast traffic running (with tcpdump), but my VLC on my local PC doesn't connect anymore.
My provider told me they had IGMP and PIM set and running.
Unfortunately I cant check the stream as I have no other available PC. And the VLC on the smartphone doesn't support udp routing.
What I misunderstood? What am I doing wrong?
Thank you Mr. Wallace for this video. Your videos and book helped me pass my Route exam. Hopefully you will produce a full video series on multicast and QoS.
Great video Kevin! It's first video for me about Multicast and I have got good understanding. Thank you for that.
Great presentation. Thanks a lot for sharing. You made Multicast-Routing so easy to understand.
Thanks sir!!
You have explained Multicast brilliantly
This is the best it could be
Hats off!!
Thanks very much! I’m glad you enjoyed the training.
Excellent and useful in real multicast scenario. You are great Mr. Kevin!!
Thanks Kevin.... This is better than reading on Cisco website.
one of the topics that ccnp dont explain, thanks for the amazing video
Best Multicast tutorial ever !
Estimated Kevin. Thank you a million for your videos, they are a invaluable contribution to the newtworking audience. Appreciate it!. Best regards from the Plurinational State of Bolivia.
What a fantastic video on Multicast !!!
Great presentation with awesome explanation.........
Salute to Kevin Wallace sir :)
Best video I watched for Multicast. Thanks Kevin
Thankyou sir. Your videos are to the point with excellent delivery. We lean a lot as well as get refreshed also.
Thanks for always making what looks like the most complex topics look like a piece of cake. Is there a Holy Kevin Grail where we can go pay homage?...lol, but on a serious note, there should be one!
Excellent explanation... Very easy to understand... Thanks Kevin....
excellent video! Thank you very much! It helped me with my CCNP ENCOR studies.

I will always like your training, very short and very informative. 100000Thx
Hi!
Can anyone please tell which simulation software he is using to demonstrate?
Great video illustrating multicast. Quick question, what if I wish to configure different RPs for different multicast groups? How does a mapping agent decide who wins the elect of RPs?

Hello Kevin, thank you for brilliant video. I was struggling understanding Distribution Tree concept until seeing your video. By the way, do you have video on PIMv6 ?
This is one of best doc created on multicast
Greeting from PAKISTAN, always beneficial, Thank you that more than word can say!
which is the best practise to chose the RP ?
Personally, I would choose a router that was centrally located topologically and had plenty of processor power.
Hi!
Kevin
Awesome video. Can you please tell which simulation software you r using?
Thank you so much for your video , which helped me to set up multi-casting in our development lab .
Many thanks Kevin, I love your way of teaching, keep going :)
Kevin is the best when it comes to Cisco , no compromise only Kevin z the guy
best Multicast Video ever !
This was a really good video, thanks Kevin. I'm glad you displayed the network diagram.
Wow excellent presentation and content . Thank you
This video just made it all click. Thanks
You made everything just easier!! :o thank you for the effort and great work!!
This is a terrific video! Thank you so much Kevin
You're very welcome! I'm gad you enjoyed it.
How can i tell if a Cisco router is currently running any type of multicast?
With RPF... what happens if you have ECMP enabled?
great and timely video, greetings from Sierra Leone
Excellent Video Sir, Awesome Content one of the best in market. Kudos to your excellent teaching skills.
Kevin,
Thank you for the usual great presentation. I have a question; why is it that in PIM Sparse mode, when a request was made by the receiver through R3 to the RP, to request Multicast traffic; why did R1 send the traffic to both RP and R3. Shouldn't R1 only send the traffic to the RP, given that R1 is also configured with the IP address of RP? I am thinking, this would have avoided the extra messaging from R3 to both source and the RP.
Thanks Kevin for the quick response; it was my oversight. I went and viewed the video again, and realized that initially, R3 was only getting traffic from just R2 (RP); not from both R1 and R2.
Thanks again for the great videos.
How would a large number of package recipients be connected to a router?
Thank you sir for giving me an understanding in multicast
You got a new subscriber, excellent video, great explanation
These videos are very, very helpful. Thank you so much.
Am I the only one that noticed the mistake on the interface used for R3 in the topology? in the draw I see that R3 has three interfaces Fa 0/0, Fa 2/0, and Fa 1/0, in the configuration demo, I kept getting lost because there is continuously used Fa 0/1 on R3 @Kevin can you confirm this is the case? there is a mistake in the labeling of the R3 interface connected to R2?
Very well done. Easy to follow, even at 1.5 time.
ip multicast-routing is same command with ip routing?
Thnx Kevin. You are videos really helpful to me. Can you do more explain video in CCNP switch series
Thanks Kevin, this video was very crisp and informative, as usual :)
Would it be possible for you to do a video on MVPN as well?
Great video and very informative. Remain blessed Kevin.
Thanks very much!
