Cisco VRF/MP-BGP Router On A Stick With Nat

The Request:

I was approached by a client who wanted me to build their multi tenant network for a small office building. During the initial meeting it came out that they already had equipment and would like to use this equipment without purchasing much more. This is what I had to work with:

  • 6 x Cisco 2960X Switches

The client also has an existing Cisco Unified Communications System that they will be configuring to provide voice services to all of the tenants.

There will be a reasonable amount of commercial grade Internet access and the tenants will be allowed to host some services locally (e-mail, collaboration software, etc.).
