Configuration Example for PPPoE over Ethernet
Example 6-1 shows a PPPoE over Ethernet configuration. In the example, the virtual template
virtual-template 1 is linked to the VPDN group. The configuration also specifies the number of sessions
allowed on the VPDN group.

Static MAC Address for PPPoE
The Static MAC Address for PPPoE feature allows you to choose the MAC address to be used as the
source MAC address for PPPoE over ATM sessions on ATM permanent virtual circuits (PVCs). You can
configure this feature for either a broadband aggregation (BBA) group or a virtual private dialup network
(VPDN) group. The feature is applied to all PPPoEoA sessions on ATM PVCs to which the BBA group
or the VPDN group is applied.
