You cannot simultaneously configure a BBA group for PPPoE and a VPDN group for PPPoE. If you
Note
configure a BBA group and then you configure a VPDN group, the protocol command in VPDN
accept-dialin configuration mode does not include an option for PPPoE (for example, you cannot specify
the protocol pppoe command). Use the no bba-group pppoe command to re-enable the pppoe option
for the protocol command.

Configuration Examples for PPPoE over IEEE 802.1Q VLANs

Example 6-4
virtual-template 1 virtual template is linked to the VPDN group. The configuration also specifies the
maximum number of sessions allowed on the VPDN group and the number of sessions allowed for each
VLAN.
Example 6-4
!Enables a virtual private dial-up network configuration on the router.
vpdn enable
!
!Creates a VPDN session group and links it to a virtual template.
vpdn-group 1
interface Loopback0
interface GigabitEthernet1/0/0
!Enables PPPoE and allows PPPoE sessions to be created through this subinterface.
interface GigabitEthernet1/0/0.10
!Configures the virtual template interface.
interface Virtual-Template1

Purpose
Returns to global configuration mode.
Specifies the interface to which you want to attach the BBA
group and enters interface configuration mode.
Enables IEEE 802.1Q encapsulation of traffic on a specified
subinterface in a VLAN. Specify the VLAN identifier.
Attaches the BBA group to the VLAN.
