Question
You are trying to bring up a new Certkiller location onto your existing frame relay network. The new location is using an Adtran router and you are having difficulties getting the site to connect via frame to your Cisco HQ router. What is the most likely cause of the problem?

A. Mismatched LMI types.


B. Incompatible encapsulation types.


C. Mismatching IP addresses.


D. Incorrect DLCI.


E. None of the above
Answers
A
Explanation:
Three LMI protocol options are available in Cisco IOS software: Cisco, ITU, and ANSI. Each LMI option is slightly different and therefore is incompatible with the other two. As long as both the DTE and DCE on each end of an access link use the same LMI standard, LMI works fine. The default LMI type in a Cisco router is Cisco. Since this is proprietary, this LMI type is incompatible with the LMI type used by other vendors.
