Introduction to Hybrid Routing Protocol:-
A Hybrid Routing Protocol has the advantage of Protocols - distance vector and Link state and message them into a new Protocol.

Difference between IGP and EGP

Interior Gateway Protocol:-

It refers to a routing Protocol that handles routing within a single autonomous system,IGPs include RIP, IGRP, EIGRP, OSPF

Extarion Gateway Protocol:-

It handles routing between different Autonomous System (AS) , Border Gateway Protocol (BGP) In an EGP

Enhanced Interior Gateway Routing Protocol (EIGRP) 

This is a Cisco proprietary enhanced distance Vector routing protocol. EIGRP has faster convergence, and has fewer network overheads, since it is uses incremental updates.

It does not send Link State Advertisement (LSA) packets as the Open Shortest Path First (OSPF) does, but sends traditional distance Vector updates containing information about networks, including the cost of reaching them from the perspective of the advertisement router. 

EIGRP, also has Link State Characteristics.

Features of EIGRP

The key features of EIGRP are aa follows:
It is hybrid routing protocol.

1. It used in large networks.
2. It provide 'Classless' routing support/LVSM Supp ort.
3. It gives auto summarization feature.
4. It support IP, IPX and Apple Talk I.e it is a 'Protocol independent' module.
5. It uses Diffusing Update Algorithm (DUAL) for best path selection.
6. It uses Reliable Transport protocol (RTP) for communication.
7. It provides a Hello packet for neighbor discovery.
8. It's administrative distance= 90
