I have already checked it. Without L3 interface IRB on primary vlan those devices in different communities don't see each other. The thing is that i need routing between community vlans.
I have got VC EX3400. Feature explorer say that it support IRB on PVLAN, but manual say it doesnt support RVI on PVLAN.
Junos allow me to configure irb on PVLAN, but it doesnt work. From switch to hosts broadcast arp requests get, but there is no answer come back to switch.
