RIP is an IGP, method of sharing shortest path info in a homogenous network. Or put another way, method of making sure IP datagrams get to the destination address and in as timely a manner as possible on the local network.

Just guessed!

RIP is an instance of a Distance Vector routing protocol. It is typically used in smaller LAN configurations where the typical hop counts will not exceed 15. RIP has two versions, version 1 and version 2. Version 1 is truly limited as it is a truly classful routing protocol in that the subnet mask is not included in the routing update packets, Version 2 this functionality was added but it is still impossible for RIP to take advantage of any variable length subnet masks. The other major limitation is, as mentioned above, RIP measures hop counts (other routers) as its metric and the ttl(time to live) on any packet is a maximum of 15, if a destination network is more than 15 hops away the 15th router will drop the packet. RIP utilizes split-horizon to attempt to avoid routing loops. Split-horizon is a method in which a router will not advertise routes learned from a certain interface back out of that same interface.
