Who’s more intelligent a rocket scientist or a lizard?
Well it’s a matter of perspective. I’ll grant you that a lizard is less likely to design a spaceship capable of inter stellar flight, but if you put that same rocket scientist in the desert, I know who my money would be on to survive the longest, the point being that the lizard has exactly the right level of skills and knowledge that it requires for its particular environment.

Imagine that you see a Tweet today inviting you to apply for a part-time networking job, something you can do in addition to your normal job. You appear to be qualified for the job, and the work looks interesting as well. However, it requires enough of your time so that you would have to set aside your current professional development plans, including study for that next Cisco certification. The job lasts one year.
Would you take the job, setting aside your certification plans for a year? How much money would you need to make in that job before it would entice you to abandon your learning and certification plans for a year?
This post works through a couple of ideas (like the above) about how to quantify the value of a certification. Many people expect that more skills and certifications will give them more Read More »

I don’t think that anyone can deny that being in the IT industry at this time is exciting and interesting. It’s also exhausting. There is a ton of hyperbole floating about on Twitter and the Blogosphere concerning the need for network engineers to become programmers, and that ‘whatever’ technology du jour is only minutes away from capturing the market and being the de-facto standard. Oh by the way, all networking gear will be white box gear too — didn’t you hear? I’ve tried to NOT write a post that I fear will be read and dismissed as mere rhetoric, but here I am anyway.
As of late, I’ve had the awesome opportunity to work with some very cool customers who are Read More »

When it comes to career development, time is a currency that must be spent wisely. I myself am a full-time dad, a full-time network engineer, and that leaves little time for personal endeavors. However we must still allocate time to develop our skillsets outside of work. Here are some tips for doing just that. Read More »

Since DMVPN has been added to the CCIE v5 BluePrint (http://www.cisco.com/web/learning/exams/docs/ccieRS_Lab5.pdf) I figured that now was just as good of a time as any to write this blog.
DMVPN stands for Dynamic Multipoint VPN and it is an effective solution for dynamic secure overlay networks.
DMVPN is combination of the following technologies:
- Multipoint GRE (mGRE)
- Next-Hop Resolution Protocol (NHRP)
- Dynamic Routing Protocol (EIGRP, RIP, OSPF, BGP)
- Dynamic IPsec encryption
- Cisco Express Forwarding (CEF)
Topology that we will be starting with:
First thing will be to complete the base configurations on R1, R2 & R3. This will consist of configuring the IP addresses on the above interfaces and setting up the routing protocol to distribute the routes. In this case we will use EIGRP 123. Read More »
