    Hi Guys,

    Can anyone give me a hint with this CCNA Intro question?

    Q3. In order to configure the routers at both ends of the WAN connections, what identification numbers will be needed from the local service providers?

    I must admit, I have been stuck on this question for a few days now. :oops: Am I looking too deeply into this or is it something simple?!

    Thanks

    Not sure, but I think it's the DLCI on a frame-relay map statement.

    Page 160 of the CCNA 4 Companion Guide Wan Technologies (Excellent book series by Cisco Press by the way).

    "The DLCI is normally a 10-bit value used to identify the Frame Relay virtual circuit. These values are typically assigned by the service provider and usually have only local significance...."

    Not nescesarily.

    Whilst you are most likely right on this one, the question didn't actually mention the WAN technology involved and for that reason the first thing to pop into my head was actually the SPID, not the DLCI :)

    True...depends on the technology. T1 would need framing and line code values (ESF and B8ZS in US probably), channels and channel speed (24 channels at 64k in US). Also possibly a bandwidth statement as well if you have several bonded T1s or ATM links so you don't go over CIR.

    Dunno...back to the drawing board on this question.

    I have The CCNA Intro Exam Cert Guide :(

    I grabbed it with much eagerness, turned to page 160 and then was promptly smashed..

    I have scanned the pages and cannot find the answer!! I'm gutted :blink

    Does anyone else have this book?

    rwilmot,

    NetEyeBall is referring to a Cisco Press book for the Cisco Networking Academy Program.

    You might want to "fall back" and get the Cisco Press Self-Study Guide for the 640-821 INTRO exam. The Self-Study Guides are designed to help you with basic foundation knowledge. The Exam Certification Guides are designed to be "last minute cramming" with a lot of summary information without the foundation depth of knowledge.

    Tartanbill,

    The SPID would come from the PSTN and not from the "Service Provider." I can understand that it could be confusing because some PSTN are also SPs. :)

    the local service provider at each end of the pvc assigns a unique DLCI (DATA LINK CONNECTION IDENTIFIER) and the DLCI should be asked about the DLCI numbers.

    hope this helps.
