I have verfied I have the correct EIGRP configuration on all of my routers and I keep getting the below error message on R1 and R6.

Does anyone know what is needed to resolve this problem. I did a search on this and it referred to possible access list or hardware problem or configuration. I am using rented equipment so I am assuming the equipment is OK. My configuration is identical to the solution guide but I continue to get these messages even after rebooting the two routers.
