Hi Mark, interesting stuff :)
Your thought is right, this is what Cisco have to say (doccd): --- Examples The following example chooses an administrative distance of 110. In this case, packets for network 10.0.0.0 will be routed to a router at 172.31.3.4 if dynamic information with an administrative distance less than 110 is not available. ip route 10.0.0.0 255.0.0.0 172.31.3.4 110 --- In your case you have an AD of 210 and EIGRP's AD is 90 which is less than 210.. so EIGRP must win the match unless the prefix it receives is less specific.. but that is not the case as you stated..
