>Let me think just an example, if a SMF sees an IPv6 address as an UPF

Thx.
I see what you are saying; this is after N3 termination and full charging, LI
and bit rate enforcement is done and to move the packet on the provided TE path
to the UPF on N9.
My original question was more on SFC functionalities that ought to be done on
N6 (I know the draft you pointed
https://tools.ietf.org/html/draft-xuclad-spring-sr-service-chaining-00 and I
still see that as alternative to NSH) and any of these have to be done on N9.
The only thing I see is TE on N9.
I think, there is no bearing on SMF for Gi LAN stuff on N6.
