To perform router installation, we need to have an IOS image. Note: Cisco has three distinct models and different chassis for all the models, If you want to make this router function as an L3 device i. GNS3 1. If you are the network engineer you must aware with the most famous network simulator that is GNS3.
GNS3 can emulate a number of different Cisco router models, but we have found Cisco and series to be the most stable in GNS3. We will use the IOS image cadventerprisek9-mz. In order to provide complete and accurate simulations, GNS3 actually uses the following emulators to run the very same operating systems as in real networks: Dynamips, the well known Cisco IOS emulator. Router, switch, and PIX and various platforms such as , , and GNS3 software is very excellent complementary tool to real work practice for Network engineer, administrator and other people who want practice and work on real cisco router and switch.
You are Sam the network engineer who is responsible for all routing within your company. Two of your colleagues called John and Hadley are having trouble reaching each other, their routers do not have any routing capabilities and they are located in different vlans. It took me s of hours reading books and doing labs, making mistakes over and over again until I mastered all the protocols for CCNA.
Would you like to be a master of networking too? In a short time without having to read page books or google the answers to your questions and browsing through forums? I collected all my knowledge and created a single ebook for you that has everything you need to know to become a master of CCNA. You will learn all the secrets about routing, VLANs, trunks, router on a stick and more.
Goal: All IP addresses have been preconfigured as specified in the topology picture.
