Stephen Farrell has entered the following ballot position for draft-ietf-mpls-mldp-node-protection-05: 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-mldp-node-protection/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- The MUST in para 2 section 3 seems to me to create a possibly new DoS enabler. The ability of N to cause this kind of ripple effect, (setting up then pushing traffic to a bunch of new LSPs), is what may be new. Exactly where in the referenced RFCs is that covered? Or am I wrong that this is a new threat? (BTW: Answering that this new threat is no worse than other existing threats if one has access to the internals of a node.... is a non-answer:-) ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- While it is fine to re-use text, it is increasingly hard to believe that almost nothing done since RFC5920 (dated in 2010) has any new security considerations. Put another way, who is really helped by a 2 line security considerations section that points at 6388 which points at 5036 (etc)?
