RFC6620 - FCFS SAVI: First-Come, First-Served Source Address Validation Improvement for Locally Assigned IPv6 Addresses

This memo describes First-Come, First-Served Source Address Validation Improvement (FCFS SAVI), a mechanism that provides source address validation for IPv6 networks using the FCFS principle. The proposed mechanism is intended to complement ingress filtering techniques to help detect and prevent source address spoofing. [STANDARDS-TRACK]

RFC6959 - Source Address Validation Improvement (SAVI) Threat Scope

The Source Address Validation Improvement (SAVI) effort aims to complement ingress filtering with finer-grained, standardized IP source address validation. This document describes threats enabled by IP source address spoofing both in the global and finer-grained context, describes currently available solutions and challenges, and provides a starting point analysis for finer-grained (host granularity) anti-spoofing work.

RFC7039 - Source Address Validation Improvement (SAVI) Framework

Source Address Validation Improvement (SAVI) methods were developed to prevent nodes attached to the same IP link from spoofing each other's IP addresses, so as to complement ingress filtering with finer-grained, standardized IP source address validation. This document is a framework document that describes and motivates the design of the SAVI methods. Particular SAVI methods are described in other documents.

RFC7219 - SEcure Neighbor Discovery (SEND) Source Address Validation Improvement (SAVI)

This memo specifies SEcure Neighbor Discovery (SEND) Source Address Validation Improvement (SAVI), a mechanism to provide source address validation using the SEND protocol. The proposed mechanism complements ingress filtering techniques to provide a finer granularity on the control of IPv6 source addresses.

RFC7513 - Source Address Validation Improvement (SAVI) Solution for DHCP

This document specifies the procedure for creating a binding between a DHCPv4/DHCPv6-assigned IP address and a binding anchor on a Source Address Validation Improvement (SAVI) device. The bindings set up by this procedure are used to filter packets with forged source IP addresses. This mechanism complements BCP 38 (RFC 2827) ingress filtering, providing finer-grained source IP address validation.

RFC8074 - Source Address Validation Improvement (SAVI) for Mixed Address Assignment Methods Scenario

In networks that use multiple techniques for address assignment, the spoofing of addresses assigned by each technique can be prevented using the appropriate Source Address Validation Improvement (SAVI) methods. This document reviews how multiple SAVI methods can coexist in a single SAVI device and how collisions are resolved when the same binding entry is discovered by two or more methods.
