Bridge tagged logical interfaces

Hi all,I am using SRX 220 as gateway to ISP. Two VLANs from ISP are terminated as a L3 logical interfaces as below:

ge-0/0/0 {
    per-unit-scheduler;
    vlan-tagging;
    encapsulation flexible-ethernet-services;
    unit 34 {
        vlan-id 34;
        }
    }
    unit 35 {
        vlan-id 35;
        family inet {
            dhcp {
                client-identifier ascii juniper;
                vendor-id juniper;
            }
        }
    }
}
ge-0/0/3 {
    flexible-vlan-tagging;
    unit 34 {
        vlan-id 34;
    }
}

I need to bridge ge-0/0/0.34 and ge-0/0/3.34.
I found a thread (http://forums.juniper.net/t5/SRX-Services-Gateway/Layer-2-and-Layer-3-logical-interfaces-on-same-physical/td-p/245068) talked about a similiar problem with me, but in that thread, he is using MPLS which I didn't.
