When IPv6-in-IPv6 tunneling is used, what is the destination IP

Yes, that is what we intended.
So a packet sent by R1 that will be forwarded outside of the ROLL
network will have a outer IPv6 header whose destination is the BR?
It wasn't clear to me whether you are proposing IPv6-in-IPv6 tunneling
for packets that come in via a border router.
Not sure I'm clear on your use case, but the restrictions in the draft
are intended to prohibit the case where an RH4 cross a RPL domain
boundary. A RH4 may be added and/or removed at a border router, but it
shouldn't process/maintain an existing RH4 across a RPL domain boundary.
Understood. My question is when the BR adds RH4, does it also
encapsulate in an outer header?
Thus is the only case when there is RH4 without IPv6-in-IPv6 when both
the source *and* the destination is a router in the ROLL network?
