Cisco NAT Cheat Sheet
I’ve always had a difficult time when attempting to remember how to implement the different types of NAT available on ASA and IOS devices. It doesn’t help that between the two device families, there are three different syntax versions used in the configurations. I created the PDF linked below as a quick reference sheet. It […]

BGP RR Design – Part 2
This is a continuation from Part 1 9. ACME VPN RR’s Design: So the current total number of PE’s dedicated for VPN functionality is around 400 (2 PE’s in each POP x 200). A full iBGP mesh between 400 PE’s comes around 79,800 sessions ((400×399) /2). By introducing two VPN RR’s each PE will have only two iBGP sessions […]

HTIRW: Reality at the Mic (1)
We’ve talked a little about the structure of the IETF, and the process a draft follows when moving from submission to draft to RFC… The perennial question is, though — why does it take so long? Or, perhaps — why is the IETF so broken? Let me begin here: the IETF is a human organization. […]

Using Python Context Managers for SSH connections
In this post, I will cover basic usage of Python’s context managers to connect to a network device using SSH. I will use them to abstract the connection establishment and teardown logic that is needed when making an SSH connection. Note: This post will not cover context manager details, as great explanations can already be found online. Instead, this article […]

Python and Jinja2 Tutorial
“How should I get started with Network Automation?” I am often asked this question by network engineers looking to build new programming skills. If you are brand new to writing Python scripts and are looking for an easy on-ramp to the network automation superhighway, I’d suggest starting with Jinja2 – the de-facto python template engine. Template building […]
