On My CCIE Lab Exam in 2001 – Day One

When I passed my CCIE in 2001, I remember both the jubilation and exhaustion of the moment. Also the loneliness, after all, my wife and children had been without a functional partner and father for more than year, and they were not there with me at the final moment.

Let me explain.

IOS: ROMMON on the C6500/Sup720 – Lesson Learned

As in, I grok my network. Also used in reference to your experience of a technology, i.e. I know multicast [...]

IOS:Open Source Lab DNS and IP Addressing

A number of Cisco Bloggers have talked about making labs available for others to use. However, part of what will be needed is some conventions to make these labs work for the largest number of people.
