Something like the following should do the trick:

router# show protocols connections interface-switch tpidrewrite
interface ge-1/0/0.123;
interface ge-1/1/1.123;

router# show interfaces ge-1/0/0
flexible-vlan-tagging;
encapsulation flexible-ethernet-services;
gigether-options {
    ethernet-switch-profile {
        tag-protocol-id [ 0x8100 0x9100 ];
    }
}
unit 123 {
    encapsulation vlan-ccc;
    vlan-tags outer 123;
    input-vlan-map pop;
    output-vlan-map {
        push;
        tag-protocol-id 0x9100;
    }
}

router# show interfaces ge-1/1/1
flexible-vlan-tagging;
encapsulation flexible-ethernet-services;
unit 123 {
    encapsulation vlan-ccc;
    vlan-tags outer 123;
    input-vlan-map pop;
    output-vlan-map push;
}
