Where are the authors? Why should we guess here? I think the authors should involve in the discussion more actively, not just posting a new version. We are all working hard together to polish and impove the draft.

Best Regards,

Hi Ron;

It is my understanding, as long as the IPv6 address is a SRv6 SID, then we must newly define its processing rules; but I don’t know if it is intent of Authors.

Cheers !

Subject: RE: draft-ietf-spring-srv6-network-programming :Section 4.16.2

I think the USD action May be necessary, because it is relative to SRv6 SID as last SID in SRH, not to related to plain ipv6 address (RFC4291);

As plain IPv6 address in DA field of IPv6 packet, it is default behavior for Node identified by DA to further Decapsulate packet in this case.

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.
