5.2.3 - Enhanced Interior Gateway Routing Protocol (EIGRP)

Flashcards covering key terms and concepts related to EIGRP and its operation.

Bandwidth

Applies a cost based on the lowest bandwidth link in the path.

Delay

Applies a cost based on the time it takes for a packet to traverse the link.

Enhanced Interior Gateway Routing Protocol (EIGRP)

A routing protocol developed by Cisco to improve upon IGRP, supporting both IPv4 and IPv6.

Difference between EIGRP and RIP

EIGRP is a distance vector protocol that uses a more complex metric based on bandwidth and delay, while RIP uses a simple hop count metric.

Topology Table

A table maintained by EIGRP that helps prevent loops and supports more maximum hops than RIP.

Hello Messaging

A method used by EIGRP to confirm connectivity with its neighbors.

EIGRP Multicast Addressing

EIGRP updates are transmitted using multicast addressing.

Protocol Number for EIGRP

EIGRP is tagged with protocol number 88 in the Protocol field of the IP header.

Convergence Performance

EIGRP is known to have the best convergence performance in many scenarios due to its efficient update method.

What is the purpose of the hello messaging in EIGRP?

To confirm connectivity with its neighbors
