Because one of the main purposes of this blog is to present and explain network protocols, I decided to create a new topology as a base topology for the followings posts.
Although I use the INE topology for my CCIE studies, I prefered to make another different. Easier to understand and quicker to configure when facing with examples. The concepts behind it are similar, a Frame relay switch for practicing frame relay exercices, redundants links with different speeds between routers to achieve multiple paths that brings me a lot of game when playing with routing protocols, redistribution… In addition I selected the 126.96.36.199/16 major network as ip address space for posterior subnetting.
For switching I will set up another new topology that I will show you later. At the moment I will focus on routing and the big family of protocols that make it possible.
As you may guessed, I will use GNS3 as network emulator. The platform selected is the well known C3725 with the adventerprisek9-mz.124-15.T5 IOS version which provides all the caracteristics we need.
