Hi Karthik, Please see inline.
Cheers, Pablo. From: spring <spring-boun...@ietf.org> On Behalf Of G. Sri Karthik Goud Sent: miércoles, 26 de agosto de 2020 0:30 To: spring@ietf.org Cc: Swamy SRK <swa...@juniper.net> Subject: [spring] PSP and USP uN Flavors Folks, In draft-filsfils-spring-net-pgm-extension-srv6-usid, a uN represents an instruction (END, END.T) instantiated on a node. Can that instruction have a PSP or USP flavor? [PC] The uN behavior is a new behavior. This behavior is defined in https://tools.ietf.org/html/draft-filsfils-spring-net-pgm-extension-srv6-usid-07#section-4.1.1 The uN behavior may be combined with the PSP, USP or USD flavors. Same applies to the uA behavior. You have the full list of behaviors in Section 9 of the draft. If so, wouldn't the PSP/USP cause an SRH that has not yet been processed to be deleted? [PC] No. Leveraging the terminology defined in Section 2 of the draft: the PSP/USP/USD is only executed when you get to the Last uSID of the uSID Container. Please have a look at the uN pseudocode in the latest revision of the draft (rev 7). I believe the pseudocode is clearer than in previous revisions. Thanks, and let me know if unclear. - Karthik Non-Juniper
