Interior Redistribution

RIP

John Neiberger is a WAN Systems Analyst for a bank based in Denver, Colorado. His background is primarily in routing and switching within an enterprise environment including IP, IPX, and SNA over a hundred-node frame relay network, with a little ISDN, DSL, and ATM thrown in. John was an Operations Supervisor at a branch of a bank before he decided to dive back into a computer-related field. Over the last four years he has attained the CCNP and CCDP certifications and is working toward CCIE.

John is married and has a two-month-old son who has turned out to be quite a distraction from studying. John's primary focus now is finding time to sleep.
