Re: [sipcore] [Technical Errata Reported] RFC7976 (5393)

Hi Ben,
thank you for your guidance.
We have discussed this during the 3GPP coordination meeting in Singapore.
Because in 3GPP we have an dependency which points to draft-jesske-update-p-visited-network-00.

At that time the proposal was to write an errata to the RFC but I'm also willing to update the RFC 7976 from Christer.
Or we update RFC 7315 which is describing the whole 3GPP P- headers.

So I'm willing to do either way.

Best Regards

Roland

Hi Roland,

When you say the 3GPP identified the need to send P-Visited-Network-ID in responses; was that an error in RFC7976 at the time of publication, or something that was realized after the RFC was published?

The former makes sense for an erratum. But situations where an RFC expresses the intent of the authors at the time of publication, but we learn later that we should have done something different are not appropriate for errata; those usually need us to update (or obsolete) the RFC through the usual processes.

Thanks!

Ben.
