ITE PC v4.0 Chapter 1 15 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Summary All routers make routing decisions by looking up information stored in their routing tables. Routes can be statically assigned by an administrator, or dynamically learned by the router via a routing protocol. Routing protocols use either distance-vector or link-state algorithms to calculate the best routes to each destination. Criteria such as ease of management, ease of configuration, and efficiency must be considered when selecting a routing protocol for use within an organization. Organizations are also called Autonomous Systems. Between Autonomous Systems, Exterior Gateway routing protocols control the flow of traffic. ISPs handle Internet traffic through the use of routing policies.
