Hi Eliot,

Thanks for the feedback! As Med mentioned we have made a small clarifying edit 
in the text. Please find the diff attached.

I’ll wait a bit before sending the new version in case there are other small 
changes to make during the WGLC process.

Thanks!
Alberto

Hi Med,

Ok, I misread that text as the processing of an error condition.

[Med] We will consider tweaking that text for better clarity.

 This raises a few questions:

What happens if an xTR wants to *add* subscriptions?  Do they just do another 
map request with the N bit set on new EIDs?

[Med] Yes.

If that same request contains EIDs that had previously had the N bit set but no 
longer do? Does the ETR just process it as it would have previously and keep 
sending map updates for those EIDs or is that an error?

[Med] EIDs with N-bit unset will be handled as per the base LISP spec. Given 
that these EIDs used to have N-bit set, updates will still be notified till the 
TTL expires for these EIDs and then:

   When the TTL for the EID-record
   expires, the EID-prefix is removed from the Map-Server's subscription
   cache.  On EID-Record removal, the Map-Server notifies the
   subscribers via a Map-Notify with TTL equal 0.

Hi Eliot, all,

The procedure to unsubscribe is covered by the following:

   If the Map-Request only has one ITR-RLOC with AFI = 0 (i.e., Unknown
   Address), the Map-Server MUST remove the subscription state for that
   xTR-ID.

We discussed among the authors back in 2017 whether the procedure should allow 
to select the EIDs for which an ITR can unsubscribe, but the agreement was to 
keep the spec simple. Hence the above text.

Cheers,
Med

Just poking my nose in here, this is a cool draft. I say, go for it.  Depending 
on implementation, it may address the very problem I was attempting to solve 
with NERD: that first dropped packet.

I have one small suggestion and a question:

The suggestion:

It would be useful to discuss what statistics should be kept when 
experimenting.  Specifically: number of subscribes (prior to or after the first 
time one saw an EID), the number of map updates over time (I’m betting there’s 
a lot of stability out there, but that’s just me), number of subscribers.

The question:

How would an xTR UNsubscribe from mapping notifications?  I would imagine this 
would amount to a new map request that clears the N bit for appropriate 
EID-Records?

Eliot

Hi All,

The authors of  draft-ietf-lisp-pubsub submitted a new version addressing the 
issues raised during SECDIR review.
The document seems mature and stable and authors are asking for formal WG Last 
Call.

This email open the usual two weeks Working Group Last Call, to end January 
28th, 2021.

Please review this WG document and let the WG know if you agree that it is 
ready to be handed over to the AD.
If you have objections, please state your reasons why, and explain what it 
would take to address your concerns.

NOTE: silence IS NOT consensus!

Thanks

Luigi & Joel
