I have a current need to perform two way redistribution of EIGRP to BGP. So the network is setup like this:
I have redundant paths between two locations. 1 of the paths is a 100MG optical ethernet. The other is a 45MG DS3 that goes to an MPLS at location 1 and a 3MG bonded pair of T-1's out of the MPLS to Location 2. I have 4 routers. 2 at each location (all 3845's). The mpls provider uses BGP and currently a routing protocol doesn't exist in my infrastructure that would be go across the 100MG connection so I planed on using EIGRP. So the MPLS links terminate to routers 1 & 2 and the Ethernet link goes between routers 3 and 4. I need to redistribute the protocols at routers 1 & 2 so as to provide redundant paths with emphisis obviously on the 100MG circuit. I'm having trouble finding information on how to succesfully weight the ethernet link and and make sure that the MPLS link stays there for the redundancy. I will use HSRP on the LAN side of these routers to create the HA for them.
