It's intended as a warning that an AS may already use LOCAL_PREF zero to mean something specific. In which case, the AS knows the specifics, authors/IETF/draft/RFC do not. I'm changing to the following reformulation. Please feel free to suggest text if you prefer. OLD: The LOCAL_PREF value must be lower than the one of the alternate path. 0 being the lowest value, it can be used in all cases, except if it already has a special meaning within the AS. NEW: The LOCAL_PREF value SHOULD be lower than the one of the alternate path. Zero being the lowest value, it MAY be used whichever LOCAL_PREF values are used by the AS. If LOCAL_PREF zero already has a special meaning within the AS, and there is a need to distinguish both usages, another low value MAY be used. > > Nits/editorial comments: > > * I suggest using RFC 8174 and its terminology boiler plate to help > disambiguate "may" versus "MAY". [Bruno] Changing reference from RFC 2119 to RFC 8174. The document already used some SHOULD. Changing: - cf above text on LOCAL_PREF 0 - A BGP speaker implementation MAY avoid such losses by ensuring that "third party" NEXT_HOPs are resolved before installing paths using these in the RIB - Alternatively, the operator (script) MAY ping third party NEXT_HOPs that are expected to be used (although both sentences are in appendix, so I'm not sure how much this apply) > * A number of acronyms are used throughout without being spelled out (e.g., > RR, IBGP, FIB, EBGP, AS), but some (e.g., ASBR) are spelled out.

[Bruno] Spelling out RR, AS I'm proposing to not spell out IBGP, EBGP and FIB which are listed as "well-known" by the RFC editor. (not to mention to readers familiar with BGP, which should be the target for this document); or leave this to the RFC editor. https://www.rfc-editor.org/materials/abbrev.expansion.txt (note that RR & AS are also part of this list, but with multiple expansions) > * In Section 1.

[Bruno] Thanks, fixed. _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
