Come with me on a ride-along about “front door VRFs”. Front-door VRFs in a tunneled environment are really quite cool but often scare people new to them. SIMPLE GRE Tunnel Example Let’s take Foxtrot13 and Foxtrot14. I hand you 2... Read More ›

As many of you know I work in Cisco’s Customer Proof of Concept (CPOC) lab and have for many years (since February of 2001). What this has meant is that for the past 14 years I’m never in one specific lab environment for more than 1 month. Which, admittedly, works great when one is a “little” A.D.D.
But for the next 5 months I will be playing (oh… right “working”) in one specific lab environment. Specifically related to Cisco’s Intelligent WAN (IWAN)
The above diagram is of the current “CPOC IWAN PreBuilt Static Testbed”. It was built late last year by CPOC engineers Robert Kintner, Steve Moore, and Gina Cornett.
Guess who will be taking this over for the next few months? I’m very stoked! …. and I’m going to take you along for the fun.
Obviously I don’t want to play and mess up the environment that is already set up and built. So tossing the below environment together for us to play and learn in. I will NOT be encrypting the DMVPN tunnels so we Continue reading
For over 30 years I’ve been in the playing in the “world of IT” and wow has that world changed a great deal in those years. But through all that change, there has been a thread, for me, that has always remained constant.

First INTEROP – ever! I’ve been feeling like a kid in a candy store trying to figure out what sessions I want to go to. The selection is vast… and the decision making has really been rough.
I’ve gotten a majority of my schedule figured out. But still lots of hard decision making ahead. It’s hard to not be able to be in multiple places at the same time. Truth be told some of those slots are just going to end up being what is “calling” to me the most on that day.
Where will I for sure be? I will absolutely and for sure be attending the following sessions!

In February of 2001 I attended a 5 day multicast class within Cisco taught by none other than Beau Williamson! In both his book and during the class, he kept referring to the multicast rendezvous point (RP) as: “a meeting place for multicast receivers and senders (almost like a multicast dating service for multicast routers)” -Developing IP Multicast Networks, […]

“Hey Fish, how good are you at BFD? None of my BFD neighbors will come up.” Two simple sentences and I am “hooked.” I love troubleshooting! Troubleshooting is just a blast for me! It’s like being a Network Detective trying to figure out “whodunit” As I sit down in front of the CLI and the […]
