Cisco Public 2 Distance Vector Routing Protocols Dynamic routing protocols help the network administrator overcome the timeconsuming and exacting process of configuring and maintaining static routes. Examples of Distance Vector routing protocols Routing Information Protocol RIP -RFC 1058. -Hop count is used as the metric for path selection. -If the hop count for a network is greater than 15 RIP cannot supply a route to that network. -Routing updates are broadcast or multicast every 30 seconds by default. Interior Gateway Routing Protocol IGRP -proprietary protocol developed by Cisco. -Bandwidth delay load and reliability are used to create a composite metric. -Routing updates are broadcast every 90 seconds by default. -IGRP is the predecessor of EIGRP and is now obsolete. Enhanced Interior Gateway Routing Protocol EIGRP -Cisco proprietary distance vector routing protocol. -It can perform unequal cost load balancing. -It uses Diffusing Update Algorithm DUAL to calculate the shortest path. -There .
