RIP (Routing Information Protocol) is one of the older routing protocols. It uses a hop count as its metric, which is limited to a maximum of 15 routers. There are two versions of RIP, version 1 transmits full updates every 30 seconds using broadcast.  Version 2 supports partial, triggered updates and uses multicast. RIP is a slow routing protocol compared to other IGP (Interior Gateway Protocols) like OSPF, EIGRP and IS-IS. Even though it’s not commonly used anymore, it is a still a great routing protocol to start with if you are new to networking.
