✦ Synopsis

A fresh look at routing and routing protocols in today's networks. A primer on the subject, but with thorough, robust coverage of an array of routing topicsWritten by a network/routing instructor who could never find quite the right book for his students -so he wrote his ownCoverage of all routing protocols. In-depth coverage of interior routing protocols, with extensive treatment of OSPF. Includes overview of BGP as wellNot written as a "pass the test" guide. Rather, a close look at real world routing with many examples, making it an excellent choice for preparing for a variety of certification examsMany extras including a networking primer, TCPIP coverage with thorough explanations of subnetting / VLSMs / CIDR addressing, route summarization, discontiguous networks, longest match principal, and more.
