OSPF Course For CCNP and Beyond: A Complete Guide

Are you trying to pass your CCNP ENCOR or ENARSI exams? Do you want to become a CCIE one day? Well then this ospf course is for you!

Complete this course and you will be able to confidently explain, configure, and troubleshoot OSPF.

Are you trying to pass your CCNP ENCOR or ENARSI exams? Do you want to become a CCIE one day? Well then this OSPF course is for you!

Complete this course and you will be able to confidently explain, configure, and troubleshoot OSPF!

A lot of solving a problem is knowing what the expected behavior or operation is so you can figure out where things went off the track. This course will give you the tools to do just that.

I am going to release at least one video per week. As I release new sections, I will update this post with links to each video and activity.

This course will include lecture style videos as well as configuration examples, troubleshooting, and lab challenges similar to what I have released in the past.

Here is a link to the playlist on YouTube.

I will update this post regularly, but make sure to subscribe on YouTube to stay up to date. For the time being, take a look at the outline below:

Network Programmability for Noobs (ENAUTO, DCAUTO, DevNet)

Using python and the NX-OS API to Configure OSPF on a device.

This script will authenticate with a Nexus device that has feature nxapi enabled. We store the token received in a variable for later use, and then enable ospf globally, set the router id, and finally configure an interface with an IP address and to participate in our ospf instance in area 0.

On my journey towards Enterprise CCIE, I might make a pit stop or two at some of the DevNet certs.

Getting started with it all can be confusing, info overload to the max, and somewhat discouraging when you’re not sure how to accomplish tasks on your own.

The point of this video was not necessarily to be an in depth tutorial, but more an overview of the thought process I used to accomplish the task of having a python script configure something on a network device, without following a tutorial.

I used the NXAPI documentation, postman, and the NXAPI sandbox to accomplish creating this script.

As I continue my path towards the Cisco ENAUTO (Automating Enterprise Networks), I will continue to post my learnings.

Please subscribe, comment with feedback on how to improve these videos, and what you would like to see in the future.

Sorry for the bit of rambling, just wanted to make a quick off the cuff video to talk about my experience with the exam and taking it at home. I hope to come back and edit this page later with more tips and resources, but for now….I need to go study this CCIE material!

Until next time! Thanks for tuning in. Make sure you get on the email list if you aren’t already.

You got this exam in the bag! Get scheduled and get passed ASAP so we can study CCIE together!

EIGRP Feasibility Condition, Offset Lists, and Variance

This post and video lesson will help you fully understand EIGRP basics such as successor routes, feasible successors, EIGRP feasibility condition, variance for unequal cost multipathing, and more!

Hey hey! Today I made a video to keep from going quarantine crazy. Has the EIGRP feasibility condition ever confused you?

Have you ever wondered what the variance command is all about, or what a feasible successor is?

Well in this EIGRP Lesson we will discuss all of these things! First we go over some key EIGRP terms and then we have a lab exercise in using an offset list and variance command to implement unequal-cost multipathing.

To make the best use of this lesson, you should have a basic understanding of configuring EIGRP. This is great studying for CCNA, CNNP ENCOR / ENARSI.

Subnetting Tutorial: Find the Network Address Given an IP

I wanted to make a subnetting tutorial that showcases my absolute favorite shortcut for finding the network address given an IP and mask.

This video shows in my opinion the fastest way to find the network address where an IP “lives”. This comes in handy when troubleshooting on the CCNA exam. Check the Video out below:

Automated Robocopy Backups With Email Notification

What happens is you schedule a task to run the first Robocopy script. Based on the error level output one of two things happen: a success or failure. If there is success you run one batch file, if it fails you run another.

The other week I was horsing around and came up with this method of backing up some files on Windows using Robocopy, and automatically sending an email of the results based on success or failure using Robocopy’s error level output codes.

There’s basically 3 parts that make this thing work:

  1. The Robocopy script or scripts
  2. Fail or Success send email script
  3. Powershell scripts to send the email based on success or failure

What happens is you schedule a task to run the first Robocopy script. Based on the error level output one of two things happen: a success or failure. If there is success you run one batch file, if it fails you run another.

That second batch file runs a PowerShell script that sends an email (saying success or fail in the subject) and attaches the Robocopy log.

Let’s dive in 🙂
