Color Code Your Routers

I came across an interesting idea, what if you could color code your devices in command line? So such as if you were operating routers at a core level you could color code the CLI to the color red, and the branch routers green and etc. I wasn’t sure if this would possible but doing some searching through the internet I found a guy Ivan Pepelnjak who wrote how to do this  a couple years ago and wrote a couple books as well, check out his blog/website at http://www.ipspace.net there is tons of helpful information along with his original guide hereContinue reading “Color Code Your Routers”

Network Troubleshooting

The thing that makes networks awesome is the fact that once you setup a network you’re not done. That may sound like a drawback but it is excellent job security! Engineers or administrators must watch the performance of an organization’s network to make sure that productivity is not affected. Network outages can have a huge effect on an organization, lost revenue and the cost of unproductive employees can severely damage the organization, Earlier this year I also talked about the troubleshooting process which goes hand in hand with network troubleshooting.

The “Ending” of Layer Two Redundancy

Although layer two redundancy should never end, this is the final chapter of understanding layer two redundancy in the network. Last week I talked about how and why STP (IEEE 802.1D) is important in the network and the problems and causes of not having it which can turn your network against you and everybody on it. Today’s post will talk about how a switch decides which one is in charge on the network and which ones aren’t Continue reading “The “Ending” of Layer Two Redundancy”

The Middle of Layer Two Redundancy

In the month of August I talked about the “beginnings” of layer two redundancy mainly looking at the basic foundations and fundamentals of having layer two redundancy. Let’s continue are discussion about redundancy in the layer two environment. Continue reading “The Middle of Layer Two Redundancy”

Link-State Protocols

Weeks ago and maybe months :), I talked about distance vector protocols and with that you probably got the feeling that when using a distance vector protocol it does not give a full network graphical representation of the entire network. Only the directly connected routes can’t remember? Check out this post Distance Vector Routing. Link state protocols are faster to converge network changes compared to distance vector however when compared to distance vector setup they can be harder to set up, maintain, and troubleshoot when problems arise.
