Martin, As per RFC 7120 early allocation process, we'd like to request AD approval for early allocation of an "Ethernet" value from the "Protocol Numbers" registry https://tools.ietf.org/html/draft-ietf-spring-srv6-network-programming-07#section-9.1 https://tools.ietf.org/html/draft-ietf-spring

Alice, To the best of my knowledge those two errata (5891 & 5890) are to be ignored. In particular because: - as of today in the errata system both errata refers to different RFCs and no errata refers to RFC 8660 https://www.rfc-editor.org/errata_search.php?eid=5890 https://www.rfc-editor.org/er

Ron, You cannot pre-select or enforce one of the two options you refer to below. The ICMP behaviors/considerations for SRv6 NET-PGM are the same as in the SRH. It boils down to: when you generate an ICMP Parameter Problem Message you follow the logic described in RFC4443 section 2.2 to choose th

Let me try asking the question a different way. (I hope I understand Ron;s question.) RFC 4443 clearly allows the ICMP source to be the destination address of the offending packet. You seem to be saying that sometimes that is okay for SRH / network programming. At the same time, the SRH d

Pablo, The problem isn't a statement in the network programming draft. It is an omission in the network programming draft. If the network programming draft unequivocally stated that a SID is a unicast address of the instantiating node, the following text from RFC 4443 would apply: "If the mes

Hello Bruno. According to the network programming draft, "Network programming combines segment routing functions, both simple and complex, to achieve a networking objective that goes beyond mere packet routing." Sadly, the document offers little insight as to what those non-routing objectives
