Re: [Idr] draft-head-idr-bgp-ls-isis-fr-01 - WG adoption call (6/6 to 6/20)

["Les Ginsberg (ginsberg)" <[e-mail]>]

Sue –

Color me confused.

We have here a protocol extension to IS-IS that the LSR WG has approved (passed last call). Which there was sufficient belief in the WG that this protocol extension was useful for it to be approved.
But you claim there is some secondary process, managed by the IDR chairs (or perhaps IDR and LSR chairs?), that determines whether the BGP-LS extensions in support of the approved IGP extensions will be allowed?
This is completely new to me – please explain how that process works.

NOTE: I am not debating Aijun’s remark as to the “enthusiasm” showed in the LSR WG for the draft – nor was I a vocal supporter of the LSR draft in question.
But, if LSR WG approval is not sufficient to justify the corresponding BGP-LS support, please explain what is the defined process and where it is documented and describe how it has been used in the past.

Thanx.

    Les

Aijun:

Thank you for your feedback on deployment issues.   It is important to know if an operator feels this option will not be deployed.

I  will contact other operators to ask them to comment on this adoption call.

Hi, all:

I don’t support its adoption.
The corresponding IS-IS document past just the LSR WG unconvincingly and I cannot foresee which operator will deploy the flood reflection mechanism in IS-IS deployment.
Then it is doubtful also the corresponding BGP-LS extension.
There is no any description for the necessary in the document.

If the authors insist to do so, I recommend to incorporate the trivia contents into the corresponding IS-IS document.

This begins a 2 week WG adoption call for draft-head-idr-bgp-ls-isis-fr-01.txt

https://datatracker.ietf.org/doc/draft-head-idr-bgp-ls-isis-fr/

  This document defines one new BGP-LS (BGP Link-State) TLV for
   Flood Reflection to match the ISIS TLV for flood reduction.

   The draft is short (5 total pages).

Since this BGP-LS feature has been adopted by IS-IS,
Please consider


  1.  Is there any technical difficulty with adding this to the BGP-LS code points?
2.   Is this draft ready for publication?
3.   Does this addition help operational networks.

Cheers, Sue Hares
