Networking Week: Implementing IPv4 Multicast Routing
Вставка
- Опубліковано 7 чер 2020
- Multicast Routing is one of the lesser understood technologies in the scope of both CCNP and CCIE certifications. In this session, we will demystify Protocol Independent Multicast (PIM)’s operations, from the PIM Register message, to building Multicast Trees with PIM Join. Once complete, you’ll be able to configure and verify IPv4 Multicast Routing with the confidence needed for either Enterprise Infrastructure or Data Center CCNP and CCIE exams!
The best way to become an expert, is to learn from one. INE continues to advance that philosophy, applying it to the digital age, and cultivating tomorrow’s leaders. Be part of a process that has worked for centuries. Find your path today: ine.com/pages/networking
Thank you Brian, as always full of information, good explanation.
Awesome as usual Brian. Thank you 🙏
Thank you, I now feel that this topic (so far) is not that complicated... I will try and build this in lab
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?
Hello Brian, great video! Can you specify when a Loopback interface would need pim. I understood from what you were saying the easiest method is to enable it on all Loopbacks but what is the technical requirement for a router doing a Join/Ping to have a Loopback interface enabled for pim?
Great video, my only wish is that it had the diagram as a link or picture to help follow along in some parts without skipping through the video.
I realize these video are published to your UA-cam channel and most likely my question was covered in the webinar information but I am not sure. Are you using Cisco's VIRL and if so what is your set up? Are you doing this on your company's VMWare servers or are you looking into an account via the web? I've not had the privilege of using Cisco's VIRL.
If you are running this on your own VMWare system, have you considered using a linux VM with a copy of VLC streaming a video clip on loop to generate your multicast video?
thanks
Due to the subtitles It is difficult to see what commands are typed .
What i do not get is in the extended ping when you specify the outbound interface as loopback0 what happens. I mean what physical interface would the ping be forwarded out of then?
it will proceed to do another lookup and then it find the physical interface to forward the traffic on. In this example the instructor used an extended ping and specified the source interface (looopback0) and the loopback IP. I wonder what happens if you only specify the source IP address (loopback IP) but not the source interface.
I need help in configuration igmp + multicast . D-link 1210
D-link .3630
For god sake, make the video quality viewable with at least 720, it's pathetic 320p is rubbish to watch
I watched the video at 720p across a satellite link without any issue. It might be your ISP's upstream connectivity that is your problem.
You can change the video quality to the maximum bandwidth your connection can support . I just watched it in 1080p
