In this short tutorial let’s configure a DHCP server on a Cisco Router. Why would we want to do that? Well configuring a basic DHCP server on a router is a good idea if this is a branch/satellite office or just a small business. There are some pros and cons of configuring DHCP on a Cisco Router so let’s briefly discuss them and then start configuring. Continue reading

Why IPv6?
Although this protocol has been around since 1996 it has been anticipated that IPv4 would one day be exhausted. In February 2011 the Internet Assigned Numbers Authority (IANA) assigned the last /8 address blocks to the Regional Internet Registries so time is getting close but you have heard this warning before right? Let’s go over IPv6 at least just an overview some the features and changes compared to IPv4 because one day it will happen it’s just a matter of when.

Part 2 – The Joys of Subnetttting – VLSM!
So here we are on Part 2 of subnetting. What makes me laugh is that I really think a lot of people over think this stuff. It’s really not the complicated and it should not scare you. Another thing to mention is that usually in the real world you usually have calculators and another pair of eyes to double-check your work unlike the exam you will need to fully understand it if you would like to pass the ICND2 or the CCNA test. So let’s get started! Continue reading
Part 1 – The Joys of Subnetting!
Since network technicians work with IP addressing, it is hugely important to understand subnetting. I remember back when I started to learn subnetting it was confusing and I wanted nothing to do with it. The thing that made me change my mind was after I understood it and how important it is. In the “Cisco world” they don’t cover useless topics, there is always a reason why they expect you to know this and it’s not just for the exams. Subnetting has always had its moments with people and in this blog I’ll do my best to show you what I have done to make subnetting an easier experience. Continue reading
EIGRP… The Basics
Enhanced Interior Gateway Routing Protocol (EIGRP) is an impressive set of features for IP Routing, which converges quickly and is on par and sometimes faster than OSPF. This routing protocol requires less processing time, less memory, and less network design than compared to OSPF. What’s the catch? This protocol is Cisco proprietary, if you have a network that uses non-Cisco routers, EIGRP will not and cannot be used on those routers. EIGRP does not really fit into a specific spot of either Link-State or Distance vector, instead it stands on its own and is called hybrid routing protocol. Continue reading
