Hi Ketan/Peter,

I am assuming this is true even in below case
"SRv6-Service-SID (END.DT4 SID)is derived from a locator corresponding to flex algorithm ? "

Thanks
Rajesh

Section3:
However, when the received route is colored with an extended color
   community 'C' and Next-Hop 'N', and the ingress PE has a valid SRv6
   Policy (C, N) associated with SID list <S1,S2, S3> [I-D.filsfils-
   spring-segment-routing-policy], then the effective SR Policy is <S1,
   S2, S3, SRv6-Service-SID>.


When we make effective SR policy cant we remove S3 from List (S3 and SRv6-Service-SID both belong to Egress).
effective SR Policy can be <S1,S2, SRv6-Service-SID>.
