Understanding the Network: A Practical Guide to Internetworking

Choosing the Right Protocol

The task of enabling IP route advertisement varies in complexity, depending on the operational scope and size of the network. Static routing, which is byfar the easiest and most problem-free method, is tedious to manage in large networks and provides no recovery facility when link failures occur. Alternatively, dynamic routing protocols address the shortcomings of static routing, but do, however, come with their own operational concerns.

Unfortunately, when selecting an IP announcement methodology, there is no single correct answer. There is, however, a wrong answer, which is to select a method that will not be able to meet the networks operational requirements or scale appropriately to enable future growth. The way ...
