Greetings:

The support for draft-zhou-idr-bgp-srmpls-elp-06 is positive, but light.
I am extending the original call to 3/3 to see if we can obtain additional support.

https://mailarchive.ietf.org/arch/msg/idr/vVpUpFP_0QqY4tzGAoeEyLM7Brc/

The text of the initial call is included below.

Cheerily, Sue

===========

his adoption begins a two week WG Adoption call for

draft-zhou-idr-bgp-srmpls-elp-06.txt

https://datatracker.ietf.org/doc/draft-zhou-idr-bgp-srmpls-elp/



The authors should respond to this message with

Email that indicates whether they know of any IPR

related to this draft.



In your discussions please consider if this WG

should approve an  extension to Segment flags defined in the

draft-ietf-idr-segment-routing-te-policy-20.txt .





The existing flags are the following



2.4.4.2.12.  Segment Flags



   The Segment Types sub-TLVs described above may contain the following

   flags in the "Flags" field defined in Section 6.8:



    0 1 2 3 4 5 6 7

   +-+-+-+-+-+-+-+-+

   |V|A|S|B|       |

   +-+-+-+-+-+-+-+-+



   Figure 22: Segment Flags



The changes proposed by this draft are the addition

Of an "E" flag to those bits.





    0 1 2 3 4 5 6 7



   +-+-+-+-+-+-+-+-+



   |V|A|S|B|E|     |



   +-+-+-+-+-+-+-+-+







E-Flag: This flag, when set, indicates that presence of < ELI, EL>



label pairs which are inserted after this segment.  E-Flag is



applicable to Segment Types A, C, D, E, F, G and H.  If E-Flag



appears with Segment Types B, I, J and K, it MUST be ignored.



Cheerily, Sue
