OSPF: Anatomy of an Internet Routing ProtocolReaders will find clear explanations of routing fundamentals, such as how a router forwards packets, IP addressing, CIDR (Classless Inter-Domain Routing), the routing table, Internet routing architecture, and the two main routing technologies - Distance Vector and link-state algorithms. OSPF is discussed in depth, with an examination of the rationale behind OSPF's design decisions and how OSPF has evolved to keep pace with the rapidly changing Internet environment. Readers will gain a sophisticated understanding of Internet routing and of the OSPF protocol in particular. Moreover, the book's practical focus will enable you to put this knowledge to work in your network environment. |
