Configuring PPPoE in a VPDN group limited PPPoE configuration options because only one PPPoE VPDN 
group with one virtual template is permitted on a device.

The PPPoE Profiles feature (bba-group) provides simplicity and flexibility in PPPoE configuration by 
separating PPPoE from VPDN configuration. The PPPoE Profiles feature allows multiple PPPoE profiles, 
each with a different configuration, to be used on a single device.
