ok this is similar to my setup in some ways.
but the picture is wrong,



remember that vr0 is not  (or at least should not be) part of the bridge.

where [R] is the IP forwarding code (i.e routing not bridging)

my profile is pppoe which is shown below
It's not completely different from yours but seems to work

I can't help you withthe bridge part but it should be ok I think.

pppoe:

  set device PPPoE:vr1
  set redial 10.3 10000
  set speed 115200           #not really intersting
  set timeout 0                  # Never time out


  disable dns
  disable ipv6cp
  disable sroutes

  set authname heyitsme
  set authkey really?
  set login
  enable lqr


  set ifaddr X.X.X.X/32 0.0.0.0/0 255.255.255.255 0.0.0.0
  add default HISADDR                    # Add a (sticky) default route
  set cd 5
