[j-nsp] Routed VLAN Interfaces on MX

I apologize for the basic question as I'm a new Junos user.  I'm attempting
to convert the following basic config from a Cisco NPE-G1:

interface GigabitEthernet0/3
 desc 'Physical link to EX'

interface GigabitEthernet0/3.41
  encapsulation dot1q
  ip address

On the MX, I am trying to configure an agg between the MX and other device
(EX), so this is the config that I have came up with:

# interfaces
ae0 {
    encapsulation flexible-ethernet-services;
    aggregated-ether-options {
        lacp {
            periodic fast;
    unit 41 {
        encapsulation vlan-bridge;
        vlan-id 41;

# interfaces irb
irb {
    unit 41 {
        family inet {

# bridge-domain
bridge-domains {
    vlan41 {
        vlan-id 41;
        interface ae0.41;
        routing-interface irb.41;

Does this configuration look correct?  Is all of this necessary?  I realize
there are several different ways to handle this in Junos.

Thanks for any suggestions or input.
