Final project about MPLS

[Divad89]

I'm about to write my final project, and I've decided it should be about implementing MPLS in a corporate network.
But here's the catch, is it possible to configure a MPLS network, not in the providers backbone, but in the intra-network for the company? And then setup a VPN-connection between the two sites of the company?
And I would be using GNS3 for simulating the network.

Thanks in advance

MPLS is not all that special it is just a bunch of virtual routers and interfaces along with a tagging system. From a corporate network standpoint it just add a layer of complexity to the router configuration. You will have the same routers at each location so why would you add the complexity to the configuration if you did not need it. In effect you would be running a routing protocol like BGP over MPLS that runs over BGP. You really only need the main BGP routing to make it all work.

I can not see a reason you would ever run MPLS in a corporate environment unless you had multiple groups within the company that were using duplicate IP blocks and needed to communicate between multiple sites. It would be as if you had multiple companies sharing the same buildings at multiple locations. It is much easier to use something like DMVPN to accomplish that.

The only place I have seen it mentioned that you might want to run MPLS inside a corporate network was when you were buying services from multiple MPLS providers and needed to connect these network works together with your own routers. It would be easier in some cases to use NNI to pass the data but again you would have to have a corporate need to have multiple virtual networks within your corporate network in the first place.

You CAN configure this since you can just treat your corporate network as a provider network but there is no practical reason to ever do it.
