a) Enhanced IGRP:
Enhanced IGRP (Interior Gateway Routing Protocol) is an advanced version of IGRP. IGRP is a distance-vector routing protocol used in computer networking. It is designed to allow routers to exchange routing information within an autonomous system (AS). Enhanced IGRP enhances the capabilities of IGRP to provide better performance and scalability.
To further explain Enhanced IGRP:
1. Enhanced IGRP incorporates several improvements over the original IGRP to enhance network performance.
2. It supports larger networks with a larger number of routers.
3. It uses a hierarchical system to divide the network into smaller areas, which allows for better routing efficiency.
4. Enhanced IGRP provides advanced features like route summarization, unequal-cost load balancing, and support for multiple IP network layer protocols.
b) Enhanced IGRP Features:
The features of Enhanced IGRP include:
1. Hierarchical Design: Enhanced IGRP divides a network into smaller areas called autonomous systems. This hierarchical structure improves routing efficiency.
2. Route Summarization: Enhanced IGRP allows routers to summarize networks and advertise them as a single route. This reduces the size of routing tables and improves network performance.
3. Unequal-Cost Load Balancing: Enhanced IGRP supports multiple paths to a destination with varying costs. Routers can distribute traffic across these paths based on a metric, providing load balancing.
4. Multiple IP Network Layer Protocol Support: Enhanced IGRP can support multiple network layer protocols, including IP, IPX, and AppleTalk, allowing for interoperability within a network.
c) Enhanced IGRP Components:
The components of Enhanced IGRP include:
1. Autonomous System (AS): An autonomous system is a grouping of routers under a single administrative domain. It can be divided further into areas for better management.
2. Router: A router is a networking device responsible for forwarding data packets between networks. In Enhanced IGRP, routers exchange routing information using routing updates.
3. Metrics: Metrics are values used to determine the optimal path for routing. In Enhanced IGRP, metrics are based on factors like bandwidth, delay, reliability, and load.
4. Neighbors: Neighbors are routers that are directly connected to each other and exchange routing updates. In Enhanced IGRP, routers exchange updates periodically to maintain routing information.
