Network design questions

Last updated on December 25, 2018

        I've been handed a project, and I'm familiar but not experienced enough to make a solid decision on this. I'm actually on the firewall side of things. We've lost our lead engineer and I'm wondering if someone can help with a sample of what would be the best setup for this. I know that OSPF would be for the LAN, and HSRP for failover between the routers on each side, but not sure about the rest of what the customer is wanting. I've included their write-up as well as the diagram:
The customer decided that it needed a redundant WAN topology to ensure that Minneapolis users have a secondary path to the main datacenter in Chicago. To do this, they purchased a private fiber line between sites. Currently, the private fiber is the primary path between Chicago and Minneapolis. Static routing is in place today to steer traffic over this line. The network director has decided that static routing is not the answer and in order to automate failover/failback between WAN paths, routing protocols should be leveraged. BGP is already in use with the MPLS provider between the CE and PE routers and this cannot be changed. You have control over all devices with the exception of the PE router. The customer has decided that eBGP, iBGP and OSPF can be used (one or a combination of all 3) and all static routes must be removed. Customer requires that the primary path be the Private fiber and secondary path be the MPLS. Minneapolis also needs to receive a default route from Chicago for internet access. enter image description here
