Configuring the PPPoE Family for an Underlying Interface

Before you begin, configure the underlying interface. When you want to configure PPPoE on an aggregated Ethernet bundle, you must configure the PPPoE family over a VLAN demux interface as an intermediate underlying option. The VLAN demux interface can be static or dynamic.

You can configure the PPPoE family on an underlying interface as an alternative to configuring PPPoE encapsulation on that interface. You cannot configure both on the same interface. You can configure the same attributes for the PPPoE family as you can for an interface configured with pppoe-underlying-options.

To configure the PPPoE family over an underlying interface:

  1. Specify the PPPoE family.
  2. (Optional) Configure an alternative access concentrator name to be used instead of the system name in PPPoE control packets for the dynamic PPPoE subscriber interface.
  3. (Optional) Attach a dynamic profile to determine the properties of the dynamic PPPoE logical interface when it is created.
