MicroNugget: What is TRILL?

Start learning cybersecurity with CBT Nuggets. courses.cbt.gg...
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.

Klaus Engelmann Thanks!

CBT Nuggets in a play musicville I was trill

[@rohanquierohero]

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.

[@edwardyeryfernandez]

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.

[@cbtnuggets]

Thank you for your feedback. We will forward your comments on to the appropriate party.

[@the1ghost764]

Excellent. I learn something new. I recently received my CCNA and I spent a lot of time understanding RSTP. Thank you CBT.

[@cbtnuggets]

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?

[@cbtnuggets]

Anthony is now a CBT Nuggets trainer and we are excited to have him on Team CBT!

[@raushanyadav2076]

Thank you sir for Excellent video.

[@antoniobosco9255]

Excellent, very nice technology! Amazing Micronugget!

[@Kopiteization]

Excellent! Just what I was looking for! Should learn a lot more to really appreciate the importance of TRILL.

[@cbtnuggets]

Edward, thanks for the feedback! How long have you been an IT professor?

[@djsubstance4146]

thx alot. i didnt know this well.

[@cbtnuggets]

Thank you! Glad that this could help.

[@abubruno]

CBT is the best

[@eno8314]

Thanks for this! Very good info

[@syberiaa]

great nugget, thx

[@cbtnuggets]

Wow! Thats a long time. What is your favorite subject to teach?

[@rohitgeralifechannelhealth3633]

Amazing

[@MrJhisson]

I thought Antony worked at SWL was there a resume generating event or something?

[@eleftheriosiliopoulos8796]

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.

[@mightystef]

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!

[@binsitt]

AFAIK IGPs work on L3, but the problem at hand occours on L2.

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.

[@MasterRyu3]

Lecture note: Anywhere he says routing, replace it with the word switching instead.

[@kracksmith4ejm1]

so has Radia sued other vendors for copyrights?

[@LFR4]

Radia actually didn't plan for STP to live long it was a hack.
