This document identifies scenarios where existing approaches for detection and mitigation of source address spoofing don't perform perfectly. Either Ingress ACL filtering [RFC3704], unicast Reverse Path Forwarding (uRPF) [RFC3704], feasible path uRPF [RFC 3704], or Enhanced Feasible-Path uRPF [RFC8704] has limitations regarding eihter automated implemetation objective or detection accuracy objective (0% false positive and 0% false negative). This document identifies two such scenarios and provides solution discussions.
