Correction, rib-group with policy is used to copy received prefixes to 
inet6.0 on in-line route-reflectors.
For off-ramp RRs to place prefixes into inet6.3 it's enough to configure 
this:
set protocols bgp group internal-v4 family inet6 labeled-unicast 
explicit-null
set protocols bgp group internal-v4 family inet6 labeled-unicast rib 
inet6.3
