Hi Swadesh, This I understood by going through the draft thoroughly. But definitely more clarification is better as you pointed. 1) So SRv6 SID TLV is used only to carry variable part ? it will never carry complete SID ? 2) Is there any case where we carry a complete SID1 in prefix SID attribute as well as complete SID2 in SRv6 SID TLV ?

Be cautious of content] Hi Rajesh, As specified in the draft-ietf-srv6-services draft, when using transposition scheme prefix SID attribute carries common part of SRv6 SID (example locator). draft-dskc-bess-bgp-car proposes to carry variable part in SRv6 SID TLV in NLRI when same scheme is used. This helps to be efficient in number of bytes consumed for each NLRI. We will clarify this in draft.
