For those who's interested, the working solution provided by JTAC is to 
place routes received via inet6 labeled-unicast session into rib inet6.3 
using rib-group. This should be done at least on route-reflectors. For 
on-ramp route-reflectors additional policy assigning "no-advertise" 
community to routes copied into inet6.0 is needed to not resend them to 
other RR_clients via inet6 unicast session without explicit-null label.

Kind regards,
Andrey
