Since IP source addresses are used by hosts and network entities to determine the origin of a packet and as a destination for return data, spoofing of IP source addresses can enable impersonation, concealment, and malicious traffic redirection. Unfortunately, the Internet architecture does not prevent IP source address spoofing [RFC6959]. Since the IP source address of a packet generally takes no role in forwarding the packet, it can be selected arbitrarily by the sending host without jeopardizing packet delivery. Extra methods are necessary for IP source address validation to augment packet forwarding with an explicit check of whether a given packet's IP source address is legitimate.

          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.
