I am trying to figure out how to route over an Ethernet drop. I have a hub and four spokes currently connected via P2P T1s. I am getting fiber from 2 different service providers here soon and was trying to get an idea of how the routing would take place over Ethernet instead of separate serial connection. I have one service provider that can drop fiber at 2 locations and another that can drop fiber at the other 2, handoff is Ethernet to me. I actually have 10 more sites but wanted to keep it small and I am hiring a Cisco CCNP/IE to do this but wanted to maybe get a jump.
How would I configure the 3845 to route to 2 different places via one drop and a bunch of different VLANS? How would I configure the 2811s to route on the other end via ethernet? I am using EIGRP routing
Current Setup (LAN side, WAN was/is just P2P, both ends ex: 10.201.201.5-6/255.255.255.252):

Hi
I think you might need some sort of gre tunneling with routing over it I'd the ISP links are Internet links and not private wan with routing exchange capability
DMVPN can be used for this type of topologies as well
Hope this help
