There appear to be two separate issues, only one of which affects this document. The issue that affects this document is that the SRH document explicitly requires that domains using SRH filter it at ingress and egress edges. That is what is relevant for the document at hand. And while some folks have envisioned use cases that violate that, the RFC is clear that it is prohibited. (My reading is that this also applies to SRv6 in general, even when compressed SIDs with no SRH are used.) The question of whether, in doing enforcing that requirement a domain may filter more packets that should not be received is about how the operator chooses to enforce the requirement. We are not specifying how the operator does the enforcement. The question of what transit domains are permitted to do is one that reasonable people appear to be able to differ on. But it is not a relevant question for this draft.

I have not asked, and do not expect, for the document to mandate or even suggest that arbitrary domains should drop packets with SRH. I will note that given that SRH is explicitly for limited domains, an operator who chooses to drop such packets is well within his rights. And I am told there are such operators. But that is not what I asked for this document. > No, that would violate rfc8200. > > O.
