Export of Source Address Validation (SAV) Information in IPFIX

This document specifies the IP Flow Information Export Information Elements to export the context and outcome of Source Address Validation enforcement data. These SAV-specific Information Elements provide detailed insight into why packets are identified as spoofed by capturing the specific SAV rules that triggered validation decisions. This operational visibility is essential for network operators to observe SAV enforcement behavior and analyze source address spoofing events detected by SAV.
