Thanks for your help. I followed your configuration but it seems not working.
I plugged in a computer at ge-0/0/3,
My configuration assumes that the traffic entering this VPLS instance must be VLAN-tagged. The traffic leaving the instance is going to be VLAN tagged. I thought this is what what You asked for by giving a vlan-id 34 in Your OP?
And Windows has a bad history regarding capturing packets with VLAN tags - it may or may not work depending on NIC card
