Re: [spring] RFC8200 update?

Hi,

> In the bearer of srv6 traffic, srv6 domain is only one part of the whole packet journey. Because the srv6 domain is trusted by single operator, it is no necessary for the outer IPv6 header (for performing SRH function) to inherit all IPv6 extension headers specially designed for the initial end-to-end IPv6 communication, for example, the AH is not must for outer IPv6 header and its SRH. Therefore, the outer IPv6 processing of srv6 traffic can appropriately relax the restrictions, that is to say, the outer IPv6 encapsulation only inherits a part of IPv6 spec.

No. It uses IPv6 and must therefore follow the rules of IPv6. What I propose is to update IPv6 to make this possible, but you can't break the rules in a standard without consensus that the rules can be changed.

> For example, it is allowed to perform functions such as PSP within SRv6 domain;  Could we treat IPv6 headers function of internal and external layers differently, after all, their purposes are different.

Let's not use implicit definitions of "internal" and "external" layers. They don't make sense in a global protocol (and despite your claims that SRv6 is limited to a specific domain, it really isn't. It uses global IPv6 addresses and can traverse the global internet). Let's define global rules that apply to everybody instead, and standardise this behaviour.
