Man, this video came out in 2010. I didn't even know what a router was 5 years ago other than it's that thing that sits under my desk at home. Totally unrelated comment

Wow, I wish that I had you as an instructor!  YOU are the best!!  Clear, concise and easily understood!  Thank you so much!!  I am in CCNA4 with Netacad and I can't tell you how much I dislike their program.  They make it so difficult to learn.  I always have to go to Youtube and view videos from greats like you to fully understand...
+Laura Dencer Yeah. I've been doing this at school on and off for a few years now. I've noticed that if you follow only the course provided curriculum, you're going to have a not so good time.

nicely explained ...except confusion could arise if you thought in terms of global dlci. as r1 would have 2 global dlci's which is not really good. should have used global dlcis of 100 200 300 per router then on r1 to reach r2  use 200 to reach r3 300 on r2 to reach r1 = 100 on r3 to reach r1 = dlci 100
I dont really feel the significance for this over basic inter-networking. This is trully needed for WAN-technologies right, I kinda miss that here. No worries though I still enjoyed the video. 
Thank you Keith. That was very informative as usual. Does it matter if you put the word "Broadcast" after each of the Frame Relay mapping commands ?
Keith Barker
The broadcast keyword allows dynamic routing protocols to send their multicast traffic over the link.    If you don't use it, the point to point frame relay connection may still work for direct traffic between the two routers.

simple, easy and crystal clear i enjoy it and learn well specially the good accent of the presenter 
Vilius Palsis
good job! great balance of clarity and details. Most of the videos i saw are either very easy and do not go into the details at all or they are very convoluted
Keith Barker
Thanks Jesse.
Jesse Cain
Thanks for the great video. For you all studying, if you go to cisco.com and search "frame relay back to back" the top couple of results are very helpful. These are in regards to setting up "back to back" scenarios that are helpful in lab situations.
Keith Barker
The frame relay switch (a separate device) has a single serial connection to each router. After that, the logical connections are done through the PVCs in frame relay.
