How many subnets do you think you will have? Are they all using
classful networks or classless network?

http://en.wikipedia.org/wiki/Classful_network
http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing

If you have a small network which is classful, you could use RIP.

Otherwise, i would probably use ospf.
http://en.wikipedia.org/wiki/Ospf

OSPF is much more scale-able, and typically used for enterprise
networks. If you are considering joining this network to some other
network, you are probably going to end up using OSPF, or maybe BGP as
the protocol between the networks. OSPF is designed for this sort of
multi-organizational networks.

quagga is a well used suite of routing protocols.
