I've been noodling on these issues for a couple of days now (many thanks to all who've been trying to help me understand), and I'm kinda confused by how some unicast address semantics could be met (or not met). Specifically: how can you ping a CSID? It's possible to ping a SID, but I don't yet see

I support the adoption of CSID draft. CSID draft defines next and replace behaviors that are consistent with the SRv6 network programming RFC8996. We've verified the solution with partners in Intel Tofino programmable switch chipset. Regards, Haitao On Fri, Oct 1, 2021 at 7:05 AM James Guichard

With regards to the chair's question, CSID is based on the single SRv6 based data plane. The addition of flavors for SRv6 compression does not mean the draft is defining multiple data planes. This is because, if we go with that logic, RFC8986, which is a product of the Spring WG has already defined

Jim, Before accepting this document, we might want to discuss why the NEXT-C-SID behavior and the REPLACE-C-SID behavior are both needed. Even if there are use cases in which one performs slightly better than the other, it the performance improvement really worth all of the additional complexit

Tom, There is a difference between C-SID and the common mobile practice.. Consider an SRv6 domain where: - The common prefix is 2001:db8::/48 - Each C-SID is 16 bits long - Node A instantiates the segment 2001:db8:1::/128 The following are all addresses of Node A: - 2001:db8:2:1::/128 - 20

Folks, It is much more simple than this. According to RFC 8200, an IPv6 Destination Address is the “128-bit address of the intended recipient of the packet (possibly not the ultimate recipient, if a Routing header is present). See [RFC4291] and Section 4.4.” Therefore, if a packet does not con
