All rights reserved. Cisco Public 1 Objectives Describe the basic features concepts of link-state routing protocols. - Distance vector routing protocols are like road signs because routers must make preferred path decisions based on a distance or metric to a network. - Link-state routing protocols are more like a road map because they create a topological map of the network and each router uses this map to determine the shortest path to each network. - The ultimate objective is that every router receives all of the link-state information about all other routers in the routing area. With this link-state information each router can create its own topological map of the network and independently calculate the shortest path to every network. List the benefits and requirements of link-state routing protocols. ITE PC v4.0 Chapter 1 2007 Cisco Systems Inc. All rights reserved.
