Routing Protocol Changes

The primary focus of this book is on routing protocols. As you read through the subsequent chapters covering protocols such as RIPng, OSPF, EIGRP, and BGP, be on the lookout for protocol-specific parameters that need to match between neighboring devices.

As one example, in Chapter 4, “Fundamental EIGRP Concepts,” you will read about EIGRP K-values and how they must match between EIGRP neighbors. Therefore, if you make a K-value change on one router, that change needs to be reflected on neighboring routers.

In addition to making adjustments to existing routing protocols, network engineers sometimes need to migrate to an entirely new routing protocol. For example, a network that was running RIP might migrate to OSPF. Two ...
