I have a ring topology scenario and I was thinking of implementing EIGRP as the dynamic routing protocol. But thinking about the EIGRP queries, I am not sure if it is a good fit for the ring. I am not an expert with OSPF but will it  a be a better fit. I currently have 10 nodes within my ring. Any thoughts will be greatly appreciated.

If you create summary address on every interface between those 10 nodes there should not be any problems with queries. So, if you plan IP address ranges carefully you will be able to summarize whole location in one summary. In the case of EIGRP IP address summarization is not only reducing size of routing table, but it is also most efficient way to resolve queries (in this case you will not have problems with queries).

On the other hand OSPF is not proprietary protocol and if needed you can mix vendors (this would be the reason to go for OSPF rather than EIGRP in the first place), but you can summarize only on ABRs.
Did you check are your device licenses support routing?

Every protocol have pros and cons.

The licenses are all good for advanced routing. Yes. I was thinking of summarization as well. Thx Predrag.
