主题: [Idr] commentsondraft-qin-idr-sr-policy-ifit-03

 

Hi authors,
 
This is an interesting topic and useful draft. After reading, I have the
following comments.
 
In section 3, it defines IFIT Attributes as sub-TLVs. And section 4 defines
each sub-TLVs for different IFIT tools.
One question is that could multiple IFIT attributes be encoded in SR Policy
SAFI NLRI?

[Fengwei]: This draft extends the sub-TLVs for encoding the information
about the SR Policy (as defined in draft-ietf-idr-segment-routing-te-policy)
to introduce IFIT attributes. Yes, an IFIT node may be capable of more than
one IFIT option types.  In this case, one or more option sub-TLVs can be
distributed along with SR policy candidate paths through BGP.

 


If so, it would be better to describe some procedures for handling these
multiple sub-TLVs.
 [Fengwei]: We will add this.


Nits:
Page 3: second line, "a per- packet" should be "a per-packet".

[Fengwei]: We will revise this.
