Chapter 7- Dynamic Routing

The cost of Dynamic Routing

Different protocols measure = bandwidth, cost, delay, hops.

Basic Information on Dynamic Routing

used since 1980's,

RIP= routing information protocol.

RIPv2

ARPANET= Advanced research projects agency network

OSPF= Open shortest path first

IS-IS= intermediate system to intermediate system.

IGRP= inferior gateway routing protocol

EIGRP= enhanced inferior gateway routing protocol ^ scaled well in larger in network implementations

BGP=border gateway protocol, (used between ISP's and larger private clients to exchange routing information

ISP= internet service provider

Routing protocols= used to facilitate the exchange of routing information between routers. (processes, algorithms and messages that exchange routing information and populate the routing table with best path).

Dynamic routing protocols= discover remote networks, maintain up to date routing info, choose best path destination, ability to find new best paths)

Data structures= routing protocols tables stored in RAM.

Routing protocol messages= messages to discover neighboring routers, exchange info learn and maintain accurate info.

Algorith- finite list of steps used by routers for facilitating info and best path.
