Are you curious to know about Interior Gateway Routing Protocol (IGRP)? Developed by Cisco, IGRP is a distance vector routing protocol that assists routers to transmit routing information within a host network. It is an interior gateway protocol (IGP) that functions within a single autonomous system. Here’s what you need to keep in mind:
IGRP Features
- Manages the flow of routing information within connected routers.
- Ensures that each router has updated routing tables with the best available path.
- Avoids routing loops by updating itself with changes occurring in the network and managing errors.
Benefits of IGRP
- Supports multiple metrics for each route, including bandwidth, delay, load, and reliability.
- Customizable metric calculation formula to compare two routes.
- The sum of segment delays and lowest segment bandwidth is the default composite IGRP metric.
- The maximum configurable number of hops for packets routed by IGRP is 255.
- Routing updates are sent every 90 seconds by default.
- Uses protocol number 9 for communication.
IGRP was designed to overcome the limitations of RIP when used in large networks. It enhances the ability of routers to handle larger and more complex networks. IGRP ensures that network traffic is transmitted through the best available path. It is a reliable and efficient protocol that simplifies routing in a complex network.
Conclusion
IGRP is a proprietary distance vector routing protocol that runs within a single autonomous system. It optimizes routing within a network by selecting the best available path for network traffic. It is an efficient and reliable protocol that makes network routing simpler in complex environments.
FAQs
What is IGRP?
IGRP stands for Interior Gateway Routing Protocol. It is a distance vector routing protocol that helps routers transmit routing information within a network.
What is the function of IGRP?
IGRP manages the flow of routing information within connected routers in a host network or autonomous system. The protocol ensures that each router has updated routing tables with the best available path. IGRP also avoids routing loops by updating itself with changes occurring in the network and managing errors.
What are the benefits of IGRP?
IGRP supports multiple metrics for each route, customizes metric calculations, configures hops for packets, and sends routing updates regularly. These features make network routing simpler and efficient.
Who invented IGRP?
IGRP was invented by Cisco.
Is IGRP reliable?
Yes, IGRP is a reliable and efficient protocol that simplifies routing in complex networks.
Final Thoughts
IGRP is a distance vector routing protocol that optimizes network traffic by selecting the best available path within a network. Its customizable features and efficient functioning make it a reliable and beneficial protocol to use for routing in complex networks.
