OSPF (Open Shortest Path First) is a type of link-state routing protocol used in computer networks. It allows routers to dynamically exchange information about the network topology, including the state and cost of each link. This information is used to calculate the shortest path to a destination network, making OSPF a reliable and efficient way […]
HSRP stands for Hot Standby Routing Protocol.We use HSRP for gateway redundancy. Our goal is for our network to have a transparentfailover in order to achieve High Availability. We want our host to auto-magically choose a next hopfor routing IP traffic in order to recover if one of our routers were to fail. So how […]
In this lab, we will run through the process of setting up a small network. We will use this network to show the different types of ACLs. We will start by using a standard named ACL in order to allow traffic to use NAT (PAT) to permit our workstation LAN network to access the internet. […]
Managing your Cisco Switches and Routers are essential to maintaining a healthy network. They’re numerous protocols, features, and technologies used throughout data centers across the globe to assist network administrators to support their network. While it would be hard to show everything in a lab all the technologies we can concentrate on core network protocols […]
I completed an example of this lab and posted the video on YouTube. You can view the video in the link below. I plan on posting more labs like the ones found on my blog on that channel. Please subscribe and leave a comment that you found the link through my blog. Generic Routing Encapsulation […]

Simple Java Program On my journey to get back to coding on a more regular basis. I decided to do a Java programming exercise where I can call different methods in a program. What better way than to practice with a classic program to calculate simple math problems. The project requirements are the following: 1- […]
A primitive data type specifies the size and type of variable values, and it has no additional methods. There are eight primitive data types in Java they are the following: byte, short, int, long, float, double, boolean and char. Below you will find a brief explanation of each primitive data types along with example Java programs using the primitive data types. Byte The byte data […]
Well here it goes. It has been years since I have programmed anything. I do dabble in scripts but to jump back into an actual computer programming language not so much. So here I will post my trials and tribulations on the road to re-learning how to program all over again. First things first. What […]
