ISDN configuration questions

[NahRamp2]

Well, I plan on retaking the CCNA very soon, and would like to know if you guys remember seeing many isdn configuration questions on the test... i didn't.

Also, whats a good tip for remembering the configuration process. I tend to get a bit confused when it comes to what the "dialer list", "dialer-goup", "dialer pool-member", and "daialer pool" commands are for and when to use them.

This is probably the most difficult part of the entire ccna for me to totally graps. Anyone clear the mental cobwebs on this one?

Practice, my friend---a lot of practice on real routers. It has been a while since I have, but if I had to, I'd configure it over and over again.

I would be more familiar with frame-relay than isdn. ISDN is completely gone from the new course versions while frame-relay is still a valid topic.

From experience, I recall when IPX and token ring were fading out, they were still "officially" testable items according to the Cisco blueprint, but they were no longer on the actual exams, especially after the course materials officially revised. I would know the core topics cold (subnetting!!!!, routing, switching, spanning tree, vlans, vtp, port security, basic access lists both named and numbered) cold. I would know PPP and frame-relay well. I would understand NAT/PAT. I personally wouldn't clutter my brain with ISDN configurations. Maybe just some theory, but I'd do that as an afterthought.

I just got my CCNP last December, and I remember an ISDN sim on the BSCI, I think...or maybe BCRAN.

The new CCNP exams don't have ISDN either. The old BCRAN did have lots of ISDN but that exam is retired.

I just took the CCNA today, and failed...again. There were definitely some ISDN questions in there. I think I had two of them. Anyway, there were several Frame-Relay questions so you need to know both of these WAN technologies. I think I screwed the Frame Relay ones up too. Need to study them more thoroughly.
