What is the Interior Gateway Routing Protocol (IGRP)?

What does IGRP stand for?

Interior Gateway Routing Protocol (IGRP) is a proprietary Distance Vector Routing Protocol used to speak Routing inFormation inside a number Network. It turned into invented with the aid of Cisco.

IGRP manages the go with the flow of routing information within connected Routers inside the Host commUnity or self sufficient Device. The Protocol ensures that each router has Routing Tables UPDATEd with the satisfactory to be had direction. IGRP additionally avoids routing Loops by way of updating itself with the Modifications taking place over the commuNity and by using errors management.

What Does Interior Gateway Routing Protocol Mean?

Cisco created InteriOR Gateway Routing Protocol (IGRP) in response to the restrictions in Routing Information Protocol (RIP), which handles a most hop be counted of 15. IGRP helps a maximum Hop Count number of up to 255. The primary purposes of IGRP are to:

• Communicate routing statistics to all linked routers inside its boundary or self sustaining gadget
• Continue updating on every occasion there is a topological, network or route excHange that occurs

IGRP sends a notification of any new adjustments, and information approximately its reputation, to its neighbors every 90 seconds.

IGRP manages a routing Table with the most ideal course to respective Nodes and to networks inside the figure community. Because it's far a distance Vector protocol, IGRP Makes use of several Parameters to calculate the Metric for the quality direction to a particular vacation spot. These parameters include put off, Bandwidth, reliability, load and most transmission unit (MTU).
