We were asked to create a Base Network in Packet Tracer. The network were supposed to have three routers, two switches and two computers. The task also specified what IP addresses the network should have, as well as subnet mask and so on.

When setting up the base network hardware, I did not concern myself too much with the physical choices. As an example, I do not use Gigabit connections. If I were, the main difference would be to change the commands in CLI from “int Fa0/0” to “int gig0/0”. My main concern in this task is to set up the network so that the units are able to ping each other properly. In real life a gigabit network would of course be a lot faster, but I would also have to install network cards that supported this on the computers in order for it to work. On this part of the base network I had some interaction with Mr. Bakke, where we discussed if it were necessary to be very specific in regards to the activity sheets specifications. After a brief interaction it was determined that for testing purposes – it was not.

When making the decision on what type of hardware to use, for this task I just took the simplest way and used the same as Mr. Drange did in lecture. And initially at first glance I thought this Base Network were quite simple, with three routers, two switches and to computers. But on closer inspection I wanted to take notice on what type of cabling were used, and why the IP addresses were “different”. At the moment I am writing this I have yet to have seen the tutorial about setting up serial cabling, and therefore had to do some quick research on it – trying to understand what this is and how it is used. As far as I can see, this is a technology normally used in WAN (Wide Area Network) and not so much in a LAN (Local Area Network). The specified “DCE” stands for Distributed Computing Environment (Rouse, 2017) and I had to install special modules into the router in order for the cabling to have a port (see image below).

After I had set the network up with proper hardware and cabling, I needed to configure the routers and computers in order to communicate properly. I did this with the following command line structure in CLI (example):

#en
#conf t
#int Fa0/0
#ip address 192.168.1.1
#no shut

After I had done this, as well as setting up the computers with IP and Default Gateway, I did a trial run of pinging from 192.168.1.3 to 192.168.3.3. This returned an error, which I at first did not understand. Until I remembered that I had not set up a routing table for the routers. And so I did:

After this was done, the base network was now up and running properly. I did the ping once again, and this is how it looked.
