Cisco Router Configuration, Second Edition

Configuring IP Routing Protocols

In the previous section, we explored establishing the routing environment and creating the routing table via static routes. Although entire networks could be run using static routes, they would be tedious to manage and would not be very responsive to outages and topology changes that could occur on a frequent basis.

To address these concerns, dynamic routing protocols were developed. Dynamic routing protocols a re algorithms that enable routers to advertise the existence of the IP network path information required to build the routing table. These algorithms also determine the selection criteria of the route that a packet follows when it is presented to the router for a switching decision. The goals of the routing ...
