There are a lot of blog posts around about the Cisco ACI technology and design tips and tricks. If you want to know more about ACI, please read the Cisco ACI Fundamentials
This post describes your first steps to create and installation of a ACI fabric. Our example design will look like this:
Our network will exist in only one datacenter with two spine switches, two leaf switches and two APIC controllers. The spine and leaf switches are connected with 40Gb/s, the APIC controllers are multihomed with 1Gb/s links.
Imagine, you can SSH to a host / server and use this SSH server as a proxy to access any local webserver (or anything else) on the local network of the SSH server… This is easily possible with PuTTY (awesome SSH client!).
As a demo, lets say we have the following topology:
We would like to manage the local firewall (192.168.1.254) from a pc on the internet. We assume that we can SSH into the SSH server.
