Zafar:

Hi!

I see the draft hasn't changed in a while. However, I do see two emails on the 
spring ML about -00 that have not received replies. Please take a look at those.

https://mailarchive.ietf.org/arch/msg/spring/Oo40eQPEFiQtcI81Qu_BzpVB5L4/
https://mailarchive.ietf.org/arch/msg/spring/Bu-wpMMoMq_wVTljkFiczPON690/

We will need more discussion on the list. Replying to those emails would be a 
good start.

In the meantime, I will put you in the queue.

Thanks!

Alvaro.

Dear chairs and WG

The authors have refreshed the draft-ietf-spring-srv6-policy-sid-list-opt and 
would like to solicit any comments/ feedback.

The draft has been stable for ~1 year.
The authors would like to request WGLC for the draft.

We look forward to the WG feedback and working with the WG to progress the 
document.

Thanks

Abstract:

   Segment Routing (SR) allows a node to steer a packet flow along any
   path.  SR Policy is an ordered list of segments (i.e., instructions)
   that represent a source-routed policy.  The packets steered into an
   SR Policy carry an ordered list of segments associated with that SR
   Policy.  An SR Policy can be instantiated SR-MPLS and SRv6 data
   planes.

   In some use cases, an SRv6 Policy's SID list ends with the policy
   endpoint's node SID, and the traffic steered (over policy) already
   ensures that it is taken to the policy endpoint.  In such cases, the
   SID list can be optimized by excluding the endpoint Node SID when
   installing the policy.  This draft specifies procedures to indicate
   whether the endpoint's node SID needs to be included or excluded when
   installing the SRv6 Policy.
