Hi, v6opsers,

While reading through RFC7084 I couldnt find a place where the CE Router 
is mandated to put a prefix in the PIO, even though there is a 
(strange?) requirement to use RIO.

I would like to ask:

- which existing particular requirement the author assumes to be putting 
a derived /64 in the PIO in the RA?

- what does it mean 'An IPv6 CE router MUST advertise itself as a router 
for the delegated prefix(es) [...] using the "Route Information Option" 
specified in Section 2.3 of [RFC4191].'?  (I am asking because I suspect 
this requirement is wrong: the CE Router must certainly not use RIO with 
these prefixes).

Alex
