Local DLCI vs. Global DLCI rant

YFZblu

Hey all--

The concept of the Global DLCI just clicked in my head, and I wanted to come here and rant about how confusing it was for me, and actually wasted a bunch of my study time. So essentially the concept of a 'Global' DLCI would really only be given by an ISP in order to make the documentation look cleaner? For n00bs like myself who don't have that mindset, seeing the 'global' DLCI makes it look like I'm mapping the remote IP address to the remote DLCI, when in fact the 'global' DLCI is the local DLCI all along - Because the DLCI's are always local.

Wow - You ever have a moment when you learn something and can almost feel a new wrinkle forming in your brain?? That just happened for me.

I know what you mean, it confused me as well when I was beginning to learn about frame relay.

This is why I love Jeremy Ciora's stuff when starting off studying. He explains important concepts like these really well, which saves alot of time later on when you go into more detailed study.

This confused me at first also. Couldn't believe I had spent that much time thinking about it after I actually figured it out

I was clueless on frame relay until I heard Jeremy's airport terminal analogy. It's the best.
