GRE Tunnels in a Hub-Spoke Topology w/ EIGRP (Lab) #1



Our company DasBoot Corp. has opened a few offices in Turkey.
The corporate offices are in sunny Izmir and there is one branch in Istanbul, and two in Ankara.

They all have basic Internet connectivity to our trusted ISP: DynamiteBBS. Which by the way is running IS-IS in its backbone with MPLS on top.

As the Network engineer of DasBoot, we decide to create tunnels in a hub-spoke fashion, connecting our branches to the corporate network. We use private addressing in our network (eg. 172.16.0.0). Here's a demonstration of running EIGRP to facilitate full connectivity between our networks. I know not too complicated but good practice and extensible lab anyways. Enjoy..
