Dear WG/Authors: This message concludes the WG Adoption call for this draft. Thank you all for your engagement during the discussion! While some have argued that defining a new SRv6 Endpoint Behavior is unnecessary in this case, there are subtle differences in the expected operation. The alloca

Hi Bruno, Thanks for your question and suggestion. Here is my understanding of the difference in the forwarding behavior: With End.X, the packet is submitted to the IPv6 module for transmission, which includes the checking of the next-hop IP address to get the corresponding MAC address. W

Hi Minxue, I have clarification questions. Looking at the specification of End.IL and End.X, the only difference seems to be End.IL: S15. Send the packet through the underlay network connection identified by S. End.X S15. Submit the packet to the IPv6 module for transmissio

Dear all, Regarding this call of adoption, I’m not yet in conditions to express my support or not at this moment, since I need to better understand the implications with the POI work in CCAMP, requiring more time from my side. However I see the inter-layer problem very interesting, of course.
