Re: IP-EIGRP: Neighbor 10.7.200.244 not on common subnet for Eth

You have configured two interfaces (from two routers) with a different network adress and interconnected these two interfaces through a hub or switch. They assume that they are on the same LAN segment as they "hear" each other through eigrp-multicasts.

You are also running EIGRP on both routers with the same A.S. number.

If you do not want the routers to exchange routing info, configure different A.S. nrs on them or disable EIGRP. If they should talk, configure them to be in the same IP subnet.

Cheers.
