Hi Byron, Thank you for your feedback. It is very important for SPRING to know which documents are important for operators. This helps defining the action items for SPRING WG. draft-ietf-spring-srv6-network-programming is a Standards Track document that focuses on technical specification for in

Ron, Let’s remain focus on the one sentence that you objected to. Network programming combines segment routing functions, both simple and complex, to achieve a networking objective that goes beyond mere packet routing. Network programming combines segment routing functions to achieve a

Hi Erik, That behavior is good, but I believe this can be formalized as: An SRv6 SID is an IPv6 address associated with the segment. When a router needs to generate an ICMP Problem Message, it MUST follow RFC4443 section 2.2 with respect to how to select the source address. The logic with respe

Zafar, Thanks for addressing this. However one thing remains. The text is now: "There MAY be additional segments preceding the END.OP/ END.OTP SID." I don't think there is a need for requirement language in that sentence, I read it as straightforward English: "There may be additional segments

Greg, I also have reservations about putting the OAM-flag in the routing header for the following reasons: * It has to be examined, even when Segments Left is equal to 0 * It is lost with PSP * It has little to do with routing

Pablo, It is difficult to see how you can add information by removing a few words. Let's begin with the text in https://mailarchive.ietf.org/arch/msg/spring/3WGuQumIfcmH281nwq3s9Un6raI. If you can see other advantages of SRv6 over SR-MPLS, we can add that information to the text in my original
