    Configuring Dynamic PPPoE over Static PPPoE with Ethernet and VLAN Interface Columns

    Figure 1 shows dynamic PPPoE subinterface columns and illustrates an alternative method for PPPoE to support multiple IP sessions over each VLAN.

VLAN Interface Columns

    To configure a VLAN subinterface to support a dynamic PPPoE subinterface:

    1. Specify a Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface.
      host1(config)#interface fastEthernet 4/1
    2. Specify VLAN as the encapsulation method.
      host1(config-if)#encapsulation vlan

      This command adds the VLAN major interface.

    3. Create a VLAN subinterface by adding a subinterface number to the interface identifier.
      host1(config-if)#interface fastEthernet 4/1.1
    4. Assign a VLAN ID for the subinterface.
      host1(config-if)#vlan id 400
    5. Set the encapsulation type to PPPoE.
      host1(config-subif)#encapsulation pppoe
    6. Assign a profile.
      host1(config-subif)#pppoe profile pppoeProfile2

      The default encapsulation type, any, applies to any autoconfigured encapsulation that does not have a specific profile assignment.

    7. Configure the interface to detect and accept dynamic PPPoE subinterfaces.
      host1(config-subif)#pppoe auto-configure
