I have reviewed the updated draft “Enhanced Feasible-Path Unicast Reverse Path Filtering” (draft-ietf-opsec-urpf-improvements-02).
This is a well written document and I believe the proposed method is certainly a more practical and effective way of implementing Source Address Validation. The Algorithms A and B provide specificity to the method and should assist the operators to better implement the recommendations. The impact on the FIB Memory is clearly described and quantified. Overall, I feel that this document will be a valuable Best Current Practice to operators. I support advancing the document.
