Roman Danyliw has entered the following ballot position for draft-ietf-mpls-egress-protection-framework-06: Discuss 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-mpls-egress-protection-framework/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- A few questions about the Security Considerations: (1) Section 11. I appreciate that this a framework document that is trying to be generic. Section 4 (and others) seem to lay out generic requirements. However, this Security Considerations section is both vague on the protocol choices (understandable) and the security services/properties they would have (the gap). For example, “The general security measures of the protocols SHOULD be used whenever applicable.” and “The available security measures of the chosen protocol SHOULD be used to achieve a secured session between the two routers.” Some discussion of what a “secured session” would look like would be helpful. (2) Section 11. What are the elements and enablers of “a certain level of trust … [being] established between the routers for the protocols to run securely”? ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- (3) Section 4. Per “The framework MUST consider minimizing disruption during deployment”, why is this MUST only to _consider_ minimizing rather than actually minimizing the disruption? (4) Section 5.7. Per “a globally unique IPv4/v6 address is assigned to a protected egress {E, P} as the identifier of the protected egress {E, P}”, I recommend being explicit and saying and s/IPv4\\v6/IPv4 or v6/ (5) Section 9. I’m missing something obvious -- what is a “label table pe2.mpls”?
