Alissa, as Les correctly pointed out privately to me, this updated text is not entirely correct. Not advertising the ELC bit can be result of: a) router not supporting this extension b) router supporting this extension, but not supporting ELC So I would rather keep the original text unchanged. This is not anything new. This ambiguity is common for any new protocol extension that signals a boolean type of information. thanks, Peter On 21/05/2020 15:09, Alissa Cooper wrote: > Thanks! > Alissa > >> On May 21, 2020, at 3:51 AM, Peter Psenak <ppsenak@cisco.com >> <mailto:ppsenak@cisco.com>> wrote: >> >> Hi Alissa, >> >> On 20/05/2020 21:57, Alissa Cooper via Datatracker wrote: >>> Alissa Cooper has entered the following ballot position for >>> draft-ietf-ospf-mpls-elc-13: No Objection >>> When responding, please keep the subject line intact and reply to all >>> email addresses included in the To and CC lines.
