Transparently Bridge two Networks using MPLS

I follow this tutorial : http://wiki.mikrotik.com/wiki/Transparently_Bridge_two_Networks_using_MPLS.

To make a LAN over public network.

But when I create the bridge and add the VPLS interface “vpls1”.

It show “disabled port” (see the image below). What is the problem ? Thank you.

The status of the VPLS interface shown as below.

The remote label and the local label is the same.

I see the tutorial is not the same number. Why ?
