What is the Enhanced Interior Gateway Routing Protocol (EIGRP)?

What does EIGRP stand for?

Enhanced Interior Gateway Routing Protocol (EIGRP) is a sophisticated Distance Vector Routing Protocol based totally at the concepts of the Interior Gateway Routing Protocol (IGRP).

EIGRP is a successor to the InteriOR Gateway Routing Protocol (IGRP). Both are owned by means of Cisco and operate handiest on their Devices. Cisco delivered EIGRP as it needed a protocol with faster converging abilties, route choice and calculation and the Capacity to report facts from neighboring gadgets.

What Does Enhanced Interior Gateway Routing Protocol Mean?

EIGRP has the following Characteristics:

1. Advanced operational perFormance
2. Capabilities of each Hyperlink country and distance Vector
3. A Classless routing protocol
4. Unique Functions which includes use of Reliable Transport Protocol (RTP), a diffusing UPDATE set of rules (DUAL), updates and updated Records about buddies
5. Faster converging as it precalculates routes and does now not broadCast hold-down timer Packets earlier than converging

EIGRP uses Bandwidth, put off, load and reliability to calculate the Metric for its Routing Table (no longer Hop Count number utilized by legacy protocols). For this cause, EIGRP Constantly selects and calculates the maximum premiere route for performance. EIGRP Makes use of a DUAL Algorithm to keep away from Loops and ship occasional whats up packets to check the status of neighbor Routers.
