Agreed (cannot claim compliance with RFC8200). Authors please comment Guys in this draft I see that all the example such as ping, traceroute to ipv6 address-> use SRH insertion rather than SRH encapsulation. This is intentionally done to reduce the packet size (since underlying data can be only ipv6) ?

Section 3.1.1 , below must be Ref2 Ref1: Hardware (microcode) just punts the packet. Software (slow path) implements the required OAM mechanism. Timestamp is not carried in the packet forwarded to the next hop. 1. 4.1.2.2, here it must be N2 (page 10) If the target SID is not locally programmed, N4 responses with the ICMPv6 message (Type: "SRv6 OAM (TBA)", Code: "SID not locally implemented (TBA)"); otherwise a success is returned. 1. 4.1.2.2, here it must be B:4:C52 (page 11) The ICMPv6 process at node N4 checks if its local SID (B:2:C31) is locally programmed or not and responds to the ICMPv6 Echo Request. 1. 4.3.2.2, here it must be B:4:C52 (page 16) The traceroute process at node N4 checks if its local SID (B:2:C31) is locally programmed. 5) in below two cases is it B5:: or it must be A:5:: ? > ping A:5:: via segment-list B:2:C31, B:4:C52 Sending 5, 100-byte ICMP Echos to B5::, timeout is 2 seconds: !!!!! > traceroute A:5:: via segment-list B:2:C31, B:4:C52 Tracing the route to B5:: Thanks Rajesh Juniper Internal -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected]<mailto:[email protected]> Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.ietf.org_mailman_listinfo_ipv6&d=DwMFaQ&c=HAkYuh63rsuhr6Scbfh0UjBXeMK-ndb3voDTXcWzoCI&r=ijfTaKShbusYK-FOvFGH9IZ538TctoQw-Pljslc0qGA&m=jrfq1dYsfk8_fBqqNNS-gdRsYxNXOt7r52G3GHN0iiQ&s=7EDIKybjxRS2y7WsSXf02B7k15AZOccvbTWWcMu0OYo&e=> --------------------------------------------------------------------
