Hi,

Just tried it to no avail:

# show vlans S-vlan1219
vlan-id 1219;
interface {
     ge-0/2/3.0 {
         mapping {
             1019 {
                 push;
             }
         }
     }
}
dot1q-tunneling {
     customer-vlans 1019;
     layer2-protocol-tunneling {
         all;
     }
}


# show vlans C-vlan1019
vlan-id 1019;
l3-interface vlan.1019;


# show interfaces vlan unit 1019
family inet {
     address 1.1.1.1/30;
}


The l3 interface vlan.1019 never comes up :(
