Robert, I would say that many of your arguments – particularly that srv6 is not exactly ipv6 – if my interpretation of your emails is correct – indicate that indeed – we seem to be in the terrain of modifying or extending things that would put this wg In violation of its own charter – and the statement made by the chairs here: https://mailarchive.ietf.org/arch/msg/spring/vCc9Ckvwu5HA-RCleV712dsA5OA/
As such – can you point me to the I-D’s for the relevant documents which permit these modifications or extensions? Or, can you clarify how what we seeing in this debate does not run up against the aforementioned statement and the wg charter?

I am not sure anyone will hardly argue that SRv6 is IPv6 or not. Maybe it is IPv6+ fully backwards compatible with IPv6. What really matters to me is that SRv6 packets can be forwarded by not SR aware IPv6 network elements with no change to data plane and control plane required. That's it - no more - no less. And so far all SPRING work on SRv6 including the draft in the subject line of this mail meets that. Kind regards, Robert On 10-Oct-21 10:04, Robert Raszuk wrote: > > Please kindly correct me if I am wrong, but where do you see that SRv6 is > mandated to use "IPv6 Interface IDs" ? I have no idea, but IPv6 is mandated to use IPv6 Interface IDs. If that doesn't apply to SRV6, then it's impossible to claim that SRV6 is IPv6. This isn't just academic standards-oriented formalism. As others have pointed out, it has very significant deployment and operational implications, given that most products support IPv6, not SRV6. Brian
