RIP is a protocol used by routers to exchange information about their routing tables. In dynamic routing, a router learns from other routers about possible routes by advertising what they know. RIP is a protocol that can do that.
RIP stands for routing information protocol. It is an intra domain routing protocol.
RIP is a routing protocol - a protocol (set of rules) that allows a router to exchange information, with other routers, about existing routes.
Rip V1 is Classful routing protocol Rip V2 is Classless routing Protocol

RIP is a IGP protocol that allows routers to advertise what they know about their routes to other routers. Since routers operate at the network layer (3), so does RIP.
Routing Information Protocol (RIP)
Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP) are two very popular Distance Vector routing protocols

RIP
If the network uses the RIP protocol, router A will determine that all paths have equal cost. If the network uses the RIP protocol, router A will update only the A-C-E path in its routing table. If the network uses the EIGRP routing protocol, router A will determine that path A-D-E has the lowest cost. If both RIP and EIGRP protocols are configured on router A, the router will use the route information that is learned by the RIP routing protocol.
