WG, Hi!

<draft-bestbar-spring-scalable-ns> advocates a couple of options for
determining which slice-aggregate the packet belongs to:
(a) Segment Range as Slice Selector
(b) Global Identifier as Slice Selector
In option (a), which is what is relevant
for draft-dong-spring-sr-for-enhanced-vpn, the following is advocated:

   ".. multiple per slice aggregate Prefix-SIDs (Slice Prefix-SIDs) can
   be assigned for the same prefix such that they all share the same IGP
   computed path over one topology and optimized for one algorithm to
   allow the steering of traffic to the same prefix along a path but
   over different slice aggregates.."

I have reviewed the latest version (rev 13) of
draft-dong-spring-sr-for-enhanced-vpn and it is good to see the above point
incorporated in section 2.3. Thanks to the authors for embracing this
important aspect – it does significantly enhance the scaling story for the
proposed solution.

Regards,
-Pavan
