Ron,

The USD flavour is used in any T.Encaps policy applied within the SR domain.

Cheers,
Pablo.

Authors,

Sorry, I meant to say USD, not USP.

Authors,

The USP flavor of the END, END.X and END.T functions isn’t needed.

USP is the default IPv6 behavior. So, if the source node specifies SID[0] as an RFC 4291 address on the SR egress node, you get the USP behavior for free.
