Network statement does not control what networks are being advertised but instead what interfaces are running EIGRP process Uses protocol number 88 Multicast to 184.108.40.206 (TTL=0) Receiving neighbour unicasts
In a small hub and spoke (where spokes are stubs) you could use On Demand Routing (ODR) to achieve full readability between sites. ODR uses CDP as its transport . CDP versions must match.
