This version incorporates changes based on comments received at the IETF-97 GROW WG meeting and also on the GROW and OPSEC lists back in November 2016. Please see the next couple of posts from me for the details of the changes made.

Name: draft-sriram-opsec-urpf-improvements Revision: 01 Title: Enhanced Feasible-Path Unicast Reverse Path Filtering Document date: 2017-05-03 Group: Individual Submission Pages: 11 URL: https://www.ietf.org/internet-drafts/draft-sriram-opsec-urpf-improvements-01.txt Status: https://datatracker.ietf.org/doc/draft-sriram-opsec-urpf-improvements/ Htmlized: https://tools.ietf.org/html/draft-sriram-opsec-urpf-improvements-01 Htmlized: https://datatracker.ietf.org/doc/html/draft-sriram-opsec-urpf-improvements-01 Diff: https://www.ietf.org/rfcdiff?url2=draft-sriram-opsec-urpf-improvements-01 Abstract: This document identifies a need for improvement of the unicast Reverse Path Filtering techniques (uRPF) [BCP84] for source address validation (SAV) [BCP38]. The strict uRPF is inflexible about directionality, the loose uRPF is oblivious to directionality, and the current feasible-path uRPF attempts to strike a balance between the two [BCP84]. However, as shown in this draft, the existing feasible-path uRPF still has short comings. This document proposes an enhanced feasible-path uRPF technique, which aims to be more flexible (in a meaningful way) about directionality than the feasible-path uRPF. It is expected to alleviate ISPs' concerns about the possibility of disrupting service for their customers, and encourage greater deployment of uRPF. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
