Hi,
We have a customer currently running MPLS across all remote sites approx 40+ sites and growing. Customer is building a DR Site across a different geographic location to provide full failover to remote sites in case of an outage back at CORE. This DR site will also have an internet connection to a different ISP Provider than what is currently used at their CORE Site. We are looking for a solution to automatically route Internet Traffic to DR site in case of an outage at CORE site. Since customer is running MPLS there is no way to inject a failover default route to remote sites since the next hop is AT&T's Routers. Can you please provide some documentation or PDF we can reference to fully accomplish this task. Customer does not want to use BGP or have their own AS # as of right now. Is there another way we can accomplish true failover between CORE and DR sites in case of Internet Connectivity outage at CORE through an MPLS network,
