Background

I’ve got a customer who has an MPLS network across several providers, tied together through my company’s network. These sites all tie back to my customer access router (CAR01) via point to hub links, coming in from major providers. All the customer’s sites are in their own VRF, with their own OSPF instance, which handles almost all the routing and local site LAN private routing.

The customer uses a “hosted firewall” company, which I’ll keep to myself, but they have issues getting them to work on stuff, so they asked us, could we bridge thier MPLS network over to Azure, through our “hub” instead of at one of the sites. Of course, sales tells them sure, we can do that! So I’m tasked with making it happen.
