[j-nsp] MX: mixin family bridge and family inet

[Tim St. Pierre]

I'm pretty sure you have to add the interfaces to the bridge domains:

vlan-200 {
     domain-type bridge;
     vlan-id 200;
     routing-interface irb.2;
++  interface xe-0/0/2.0;
  }

We use a similar setup on MX, and it works well.
