Ron, In the example you listed the SRv6 implementation does not reply sending an ICMPv6 Parameter Problem message. As you said, this would be a violation of RFC4443. I believe that RFC4443 is very clear about this.
Thanks, Pablo. From: spring <[email protected]> on behalf of Ron Bonica <[email protected]> Date: Monday, 25 November 2019 at 20:22 To: SPRING WG <[email protected]> Subject: [spring] SRv6 And ICMP Processing Pablo, Assume that an SRv6 implementation receives the following packet: - IPv6 Header o Destination Address is a locally instantiated END.DX4 SID o Next Header is ICMPv6 - ICMPv6 Header o Type is Parameter Problem Section 4.5 of draft-ietf-spring-srv6-network-programming-05 suggests that the implementation would respond by sending another ICMPv6 Parameter Problem message. This would violate RFC 4443, Section 2.4.e. You might want to add some text to the draft stating compliance with the rules in Section 2.4 of RFC 4443. ROn Juniper Business Use Only
