Re: [Lsr] RtgDir Last Call Review: draft-ietf-ospf-sr-yang

[tom petch <[e-mail]>]

My previous message said I was happy with router-id in this i-d.

No I am not.  I was looking at draft-ietf-<the other IGP>-sr-yang.

I think that this I-D is in error to create its own version of router-id when rfc8294 has defined one for the IETF to use (and RFC8294 which defines it is already an import).

I see other minor glitches which I hope to flag next week.

Hi Tom,

That looks to me like a human mistake on the CC'ed recipients. Using the
directorate web form may have prevented it, but that would have been
much less fun.

Thanks for your careful checking. I'd be happy to hear your opinion on
the router-id type.
