In EIGRP, the network statement specifies which interfaces are going to
participate in the routing process. So, for every separate major network on
the router, you need a different network statement.
For example, on Router eo1 the only interface that will run EIGRP is e0. To
have EIGRP run on all interfaces on that router, add "network 10.0.0.0".
Do that for the necessary networks on each router and you should be good to
go!
