Re: [Isis-wg] [spring] working group last call for draft-ietf-spring-segment-routing

Hi Chairs,

I currently have some issue with the anycast section of the draft. Based on the discussion  we had during the WG session (through Pushpasis's presentation), it looks that the anycast section is not enough explained (what is the problem behind ...) and using a "MUST" for mandating "common SRGB" is too restrictive to me as it was decided by the WG to make the SR architecture working with different SRGB per node.
I'm completely in favor of using "common SRGB" between anycast nodes as short term solution if possible, but working on general solution is also necessary.

Some more explanations are necessary, and a recommendation rather than using a MUST would be better.

PS : also the anycast draft refers to N-bit unset which is an encoding reference and so does not really make sense in this draft, possible solutions :
- move the statement to ISIS and OSPF draft
- be more generic on explaining the constraint (no more reference to encoding)

Regards,

Stephane

Dear SPRING WG (and cc MPLS, OSPF, IS-IS, 6MAN, please include SPRING in replies per the reply-to):

As we discussed at the SPRING meeting yesterday, working group last call has been requested for draft-ietf-spring-segment-routing. Please reply to the list with your comments, including although not limited to whether or not you support advancing the document to RFC. Non-authors are especially encouraged to comment.

In consideration of the fact that a number of WG calls are going on concurrently, we will end the call on August 31, 2015. 

Authors, please indicate whether you are aware of any relevant IPR and if so, whether it has been disclosed. (Please do this even if you've done it before, thanks for your help.)

Thanks,

--Bruno and John
