In this video, Anthony Sequeira covers TRILL. Back when building large Layer 2 networks seemed like the best way to scale up to hundreds of nodes, STP's original developer created TRILL to make use of IS-IS and ECMP. Watch to learn about TRILL's history and the routing technology it uses.
Through the leveraging of ECMP and IS-IS, Radia Perlman proposed TRILL as an alternative to the complexity of spanning tree technologies like STP, RSTP and MSTP. For its part, STP enabled redundant paths in the Layer 2 Domain by dynamically blocking particular links so there wouldn't be any loops in the topology. But that had a drawback: some links end up getting rendered useless when STP blocks them in particular topologies - even if we're paying for those links in bandwidth. TRILL was introduced as a replacement to STP and was based on the idea of scaling upward by way of Layer 2. By drawing from Layer 2 routing intelligences like IS-IS and ECMP, TRILL worked to accommodate tremendous numbers of nodes with lots of redundant connectivity.

Happy Monday Nugget Fans! Start your week off with Anthony Sequeira's newest MicroNugget and learn about Trill: th-cam.com/video/I7mvUrc90jQ/w-d-xo.html
Amazing !!!
Another great micronugget !!!
Klaus Engelmann Thanks!
CBT Nuggets in a play musicville I was trill
I read TRILL an year and half so and from that time, I had an idea of it but I thanks to u for refreshing it. Crisp and clear.
Excelente Anthony, blessing and thanks to everyone at CBT. I am an IT professor and I am more than please to see the quality of your pedagogy and team work. Keep it up.
Thank you for your feedback. We will forward your comments on to the appropriate party.
Excellent. I learn something new. I recently received my CCNA and I spent a lot of time understanding RSTP. Thank you CBT.
First off, Congratulations on receiving your CCNA Christian! #conquer Also, we appreciate the feedback on this MicroNugget. What do you plan on training for next?
Anthony is now a CBT Nuggets trainer and we are excited to have him on Team CBT!
Thank you sir for Excellent video.
Excellent, very nice technology! Amazing Micronugget!
Excellent! Just what I was looking for! Should learn a lot more to really appreciate the importance of TRILL.
Edward, thanks for the feedback! How long have you been an IT professor?
thx alot. i didnt know this well.
Thank you! Glad that this could help.
CBT is the best
Thanks for this! Very good info
great nugget, thx
Wow! Thats a long time. What is your favorite subject to teach?
Amazing
I thought Antony worked at SWL was there a resume generating event or something?
Anthony Sequeira, based on your experience, can ccna dc be combined with any microsoft certification path? thank you in advance. I wish a happy new year.
Awesome explanation regarding TRILL!
However, I have to understand why, in 2017, it still pertinent to make an L2 network architecture that uses an IGP to eliminate loops and broadcast (like TRILL) instead of directly making a routed architecture using an IGP !?!
If you have an answer for me Anthony, it will be very appreciated 😉 Thanks!
AFAIK IGPs work on L3, but the problem at hand occours on L2.

Can you try and replace this video with a less happier version ... i mean he sounds tooo happy ... through the whole video ... he doing a good job in teaching though .. would love to get another video from the person .. just a bit normal in tone .. just like the above comment says .. thanks
Trill are depicted as comprising a humanoid host, and a worm-shaped symbiont that is implanted in the host's abdomen. Their personalities are a combination of the host and symbiont, with the symbiont's memories providing continuity between hosts. Their home world, also named Trill, is a planet in the Alpha Quadrant, the primary setting of most of the Star Trek series.
Lecture note: Anywhere he says routing, replace it with the word switching instead.
so has Radia sued other vendors for copyrights?
Radia actually didn't plan for STP to live long it was a hack.
