Hi Wang,

You are correct. Though I wouldn¡¯t call it a goal but rather a benefit/advantage ¨C same applies to SR-MPLS where the label stack can be reduced.

Thanks,
Ketan

Subject: [Lsr] draft-ietf-lsr-flex-algo

Hi authors:

After reading through this draft lsr-flex-algo, I want to know whether there is a potential goal of this draft to reduce the SRH size with enabling flex-algo with admin group in SRv6 deployment, because without flex-algo we have to have a big SRH size when the SRH include more SRv6 SIDs, if we enable flex-algo under special topology and link constraint condition, in theory we can even construct  a end to end SR path/tunnel without SRH, but it still meet TE requirement. So my question is whether the flex-algo can be used as tool to reduce SRH size?



Cheers !
