Attached the topology diagram.
in general i'm running EIGRP at the sites within providers 2 and 3 with process #1, and OSPF area 0 at the core devices in the HQ.
Any ideas about this design?
i'm planning to apply EIGRP at the sites within provider1, do i configured them the same EIGRP process #?
i'm sending only default routes to the remote sites
Thanks
