Explain the concepts of IGRP(Interior gateway protocol). Explain how it works

Interior Gateway Routing Protocol is the proprietary protocol developed by CISCO for addressing the issues associated with routing in large and heterogeneous networks. Bandwidth, reliability, delay, maximum packet size and load are factors for calculating routing metric using mathematical formula. The smallest calculated metric is considered as the least-cost path. Split horizons and hold-downs concepts are implemented for addressing looping loop issues.
Networking - Concept of EIGRP(Enhanced interior gateway routing protocol)
Concept of EIGRP(Enhanced interior gateway routing protocol) - EIGRP transmits the subnet mask for each routing entry by which EIGRP’s VLSM and route summarization is enabled........
Networking - Explain the different types of packets in EIGRP
Explain the different types of packets in EIGRP - Hello Packets: EIGRP neighbor ship is discovered and maintained by Hello Packets. If the router fails to receive a hello packet within the hold timer, the corresponding router will be declared dead. .......
