You can't get your Cisco ASA to work with CenturyLink's GPON DSL product on a cisco ASA 5506

So CenturyLink has a new product called GPON.  It is delivered via a DSL modem connected to an Adtran TA324 which is connected via Fiber to their backbone.  The service utilized PPPOE however I couldn't make this work to save my life.

Turns out, you have to tage VLAN 201.  On an ASA 5506 / 5512 this is how you do it-

interface GigabitEthernet1/2
 description Connection to Clink GPON DSL
 no nameif
 no security-level
 no ip address
interface GigabitEthernet1/2.201
 vlan 201
 nameif outside
 security-level 0
 pppoe client vpdn group Qwest
 ip address pppoe setroute

  1. Do you have the ASA full config? (obviously obscuring the password?)
