Krzysztof thanks for the link, to me it does seem that Juniper sees SRH insertion for TILFA as desirable, as documented in draft-voyer-6man-extension-header-insertion.

So Dan, I think we can jump to that conclusion supported by 19 implementations and 5 deployments as captured in draft-matsushima-spring-srv6-deployment-status, including Juniper's.

Ron, yes – I echo Eric – all my respect.

Ron, I for one, would jump to conclusion for that specific use case where insertion is performed, and have the expected behaviour. This is the exact use case that was described over the years in this mailing list,

Now, obviously, this use case is contain within the operator domain. I don’t expect an operator to have “TI-LFA” on their peering links with other transit/operator.

For people references, page 15 “TI-LFA over SRv6”:

Folks,

My apologies to Zafar Ali. Reading through the EANTC report, it appears the Juniper demonstration SRv6 Routing Header insertion to support TI-LFA. In that respect, Zafar is correct.

However, we should not jump to the conclusion that such behavior is desirable.

                                                                       Ron
