What is RIP

what is RIP a brief overview

There is RIP routing, and then there is IGRIP routing.  These two protocols help to guide traffic
around on the Internet.  Specifically, RIP is used to manage the number of successive hops a packet
of data must take.  RIP is used within a network to handle access hops within the network, and
IGRIP is used for handling data packets which are actually addressed outside the current domain.

RIP limits the hops a packet must go through to 15, while IGRIP ups the total hops to 255.  RIP is
called a “distance vector protocol” and routers stay updated on a usually regular basis of around 30
seconds for most.  It is discussed in RFC 1058, and RFC 1723.

The default number of hops for a packet to take is one.  If a single hop is not available, which is
usually the case with a server centralized network, then the shortest available route is calculated,
which must be less than 15 hops total. Where IGRIP is an Internet Gateway, RIP is used internally,
and mages packets bound for locations within the physical domain, or network.  Any hop with a
metric count of greater than 15 hops is considered unreachable and undeliverable.

RIP, however, is being replaced by Routing Information Protocol v2, which extends the rules that
RIP established.  For more information about RIPv2, visit:
