Source Address Validation at the Edge: SAVI, uRPF, and Multi-Prefix Hosts

By: Relington, James

Source Address Validation at the Edge: SAVI, uRPF, and Multi-Prefix Hosts explores the technical, architectural, and operational foundations of verifying the legitimacy of source IP addresses across modern networks. Through detailed analysis of mechanisms like uRPF, SAVI, and DHCP snooping, and with deep dives into real-world case studies from ISPs, enterprises, and campuses, the book examines how spoofing prevention can be engineered, automated, and scaled. It connects legacy best practices such as BCP 38 and BCP 84 with cutting-edge developments like the IETF SAVNET initiative, addressing challenges in asymmetric routing, virtualization, cloud environments, and multi-prefix hosts. Combining theory, design, and implementation insight, it provides a complete roadmap toward building trustworthy networks that enforce source integrity at every edge.
