Alia Atlas has entered the following ballot position for draft-ietf-pals-vccv-for-gal-05: Yes When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-pals-vccv-for-gal/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- 1) In the last paragraph of Section 3: " Note that the inclusion of a GAL following the PW LSE over a label switched path subject to Equal-Cost Multi-path (ECMP) load balancing can cause the OAM packet to take a different path through the network from the corresponding PW data packets. If that is not acceptable, then an alternative VCCV type needs to be used." Since the GAL is a Reserved label, it should not be included in a hash done for load-balancing. This is described in RFC 7325 Sec 2.4.5.1 bullet 3 " Special-purpose labels (label values 0-15) MUST NOT be used. Extended special-purpose labels (any label following label 15) MUST NOT be used. In particular, GAL and RA MUST NOT be used so that OAM traffic follows the same path as payload packets with the same label stack." Please correct the paragraph to add this reference. I know that there may be old implementations out there that do the wrong thing - but an RFC should refer to the correct behavior. The sentence in Section 7 " Attention is drawn to the possible absence of fate sharing between PW data packets and VCCV CC Type 4 packets described in Section 3 and Section 4." will also need updating. 2) The use of LSE as an unintroduced abbreviation is slightly confusing. Can you please expand it the first time to Label Stack Entry?
