Acronym for Routing Information Protocol.
RIP is an simplistic interior distance vector routing protocol. RIPv1 in particular is very hidious, however RIP is generally used because it's just so easy to setup and "just works".
Acronym for Raster Image Processor
A hardware/software combination that converts a vector image into a raster image. All PostScript printers contain a RIP that converts the PostScript commands into bitmapped pages that the printer can output.
Acronym for Rest In Peace
RIP is a distance vector router which sends updates which comprise of the entire routing table every 30 seconds to each neighbor. RIPv1 broadcasts this information out of all the router interfaces which are partaking in the RIP process, whereas RIPv2 multicasts this information the same way using 188.8.131.52.
RIPv1 does not support VLSM (Variable Length Subnet Masking) whereas RIPv2 does. RIPv1 is a classful routing protocol, which does not carry the subnet mask with it's routing updates. RIPv2 is a classless routing protocol which means the subnet mask is included and carried with each routing update.
RIPs routing metric uses hop count and does not account for available bandwidth or the propagation delay of the link. Any particular route can be advertised 15 hops, once the hop count reaches 16, the network is considered unreachable.
RIP Routing, like any other distance vector routing protocol, has the following characteristics...
