Do not use RIP. There are really only two options to choose from, EIGRP and OSPF. OSPF is a standard and EIGRP is Cisco's. So if you are connecting to differnet types of routers, OSPF is the choice to use. If nothing but Cisco than choose EIGRP. It really comes down to knowing the protocol itself and personal preference.

Depending on the equipment in your network, you have a limited set (essentially only RIP for L3 switches with standard Image) or an almost full set (for L3 switches with enhanced image) of routing protocols to choose from.
If there are no alternative routes possible in your network(no redundancy), then even static routes would work fine, but this approach does not scale well.
When only RIP is supported on some of your equipment, try using RIPv2. It at least advertises classless routing information. Normally RIP is painfully slow in converging after a link/node failure. It can mean gaps in connectivity of tens of seconds till more than a minute.
When all L3 switches and routers support OSPF, then that is a better choice, as the unavailability of the network is much shorter.
There are more compex cases possible, where one section of the equipment runs RIP, and another section of the network runs OSPF.
In such cases route redistribution of routing information learned via one routing protocol (e.g. RIP) must be injected into the other protocol (e.g. OSPF) and the other way round,so that routing to all parts of the network is guaranteed from all parts of the network.
You can also redistribute static routes and connected subnets explicitly and modify the default settings (such as metrics) during the redistribution.
Please read up on these issues. There is plenty on the web, e.g. at
http://www.cisco.com/univercd/cc/td/doc/cisintwk/idg4/nd2003.htm
http://www.cisco.com/univercd/cc/td/doc/cisintwk/idg4/nd2014.htm
It may be a starting point.
Good luck.

Hi,
To answer this question effectively, let us know about the brief overview of the Network Setup to be implemented.
