Hi There,
Currently I'm trying to configure private vlans on EX 4200.
Requirement to configure private vlans accross switches is to have junos
10.4R1, seefollowing link:
About adding vlans, when you are configuring private vlans on EX4200 , you
do not need vlan-id-s, community names are enough. but if you want to span
PVLAN across switches , you will need additional vlan-id to use, within
trunk port.
One more link about PVLANs:

Best Regards,
