Earlier this week, I finished the CBTNuggets ICND 101 video series. I was pleasantly surprised at the quality of the videos, and I did learn a lot of information from the videos. These videos provided plenty of theory along with hands on examples. As noted in previous posts, I used the GNS3 simulator to complete the hands on practice, and the combination of videos and hands on valuable.
No that I’m done with the videos, I’ll look to take a couple practice tests and continue studying, and hopefully, this will set me up for a successful test. I have to figure out how to schedule a test, so I will provide an update at that time.
I started to use GNS3 to assist in studying for my CCNA, and once completed with the CCNA, I will move onto the CCNP cert which will have new courses\tests starting in Feb 2015. GNS3 does have provisions for a “Virtual PC System’ in the software; however, I feel that I wanted\needed a platform that has more capability to ensure proper configurations of the scenarios.
To solve this issue, I use a router image as the end point (PC function) in the practice scenarios, and it is rather easy to config a router for this function. The advantage of using a router is that it has a lot more functionality than the VPCS provided, and you should be very familiar with the commands for the Cisco IOS.
To create a PC from the router IOS, there are a few simple steps to follow.
1. Drag and drop a router image into the scenario
2. Right click on the router, select change icon and select the PC icon
3. Right click on the new PC icon (previously the router icon) select configure and rename it from Rx to PCx. The element has to be in the “stopped” state.
4. Now the end-point looks like a host, so I make a couple config changes. In global config execute the “no ip routing” command and “ip route 0.0.0.0 0.0.0.0 <default GW IP>
