Improved Interior Gateway Routing Protocol (EIGRP) was presented as a distance-vector directing convention in 1992. It was initially intended to function as a Cisco restrictive convention on Cisco gadgets as it were. In 2013, Enhanced Interior Gateway Routing Protocol turned into a multi-seller directing convention.
Upgraded Interior Gateway Routing Protocol is a high level adaptation of IGRP that allows switches to trade data more productively than then past organization conventions. As the name recommended, Enhanced Interior Gateway Routing Protocol is an improvement of IGRP(Interior Gateway Routing Protocol). IGRP is out of date since IOS 12.3 delivery. It was a classful, distance vector directing convention.
Improved Interior Gateway Routing Protocol is a distance vector directing convention with highlights of connection state steering conventions. It is appropriate for a wide range of geographies and media. In an all around planned organization, Enhanced Interior Gateway Routing Protocol can scale to incorporate various geographies and can furnish very fast combination times with insignificant organization traffic.
Improved Interior Gateway Routing Protocol is otherwise called the half and half directing convention in some more established documentation. Be that as it may, this term is misleading on the grounds that Enhanced Interior Gateway Routing Protocol is definitely not a half and half between distance vector and connection state directing conventions. Upgraded Interior Gateway Routing Protocol is just a distance vector directing convention.
Switches utilizing either Enhanced Interior Gateway Routing Protocol and IGRP can interoperate in light of the fact that the measurement utilized with one convention can be converted into the measurements of the other convention. Improved Interior Gateway Routing Protocol can be utilized for Internet Protocol (IP) organizations yet additionally for AppleTalk and Novell NetWare organizations.
Highlights of EIGRP
Upgraded Interior Gateway Routing Protocol is a directing convention which incorporates elements of both connection state and distance vector steering conventions. Nonetheless, the critical standards of Enhanced Interior Gateway Routing Protocol are as yet in view of the key distance vector steering convention, since it gets data from straightforwardly associated neighbors. EIGRP is a high level adaptation of the distance vector steering convention since it remembers highlights not found for some other distance vector directing conventions.
Diffusing Update Algorithm (DUAL)
The diffusing update calculation (DUAL) is the calculation utilized by EIGRP directing convention to ensure that a given course is recalculated around the world at whatever point it could cause a steering circle. It is ensures circle free and reinforcement ways all through the steering area. EIGRP store all suitable reinforcement courses utilizing DUAL and afterward adjust the course when required.
Laying out Neighbor Adjacencies
EIGRP lays out Neighbor adjacencies with straightforwardly associated switches that are likewise empowered EIGRP to follow the situation with these straightforwardly associated switches.
Solid Transport Protocol
EIGRP relies on restrictive convention Reliable Transport Protocol (RTP) to give conveyance of EIGRP bundles to neighbors. RTP and the following of neighbor adjacencies set up for DUAL.
Fractional and Bounded Updates
Not at all like RIP, EIGRP not sending any intermittent updates and course sections since it doesn’t progress in years out. It employments “halfway and limited” terms for refreshes. The term halfway use for update just incorporates data about the course changes, for instance, another connection or a connection becoming inaccessible. The term limited means proliferation of fractional updates that are sent distinctly to those switches that the progressions influence. Incomplete and fortified update limits the data transfer capacity for EIGRP refreshes.
Equivalent and Unequal Cost Load Balancing
EIGRP upholds both equivalent and inconsistent expense load adjusting. Equivalent and Unequal expense load adjusting permits better traffic stream in the organization. It is conceivable because of changing the worth of difference. The default, the difference is 1, thusly, upholds equivalent expense load adjusting however to utilize inconsistent expense load adjusting then we can change the worth of fluctuation as per how much traffic we need to part across various ways.
