Configuring Dynamic PPPoE over Static PPPoE with Ethernet Interface Columns

Figure 1 shows dynamic PPPoE subinterface columns configured over an Ethernet interface without VLANs.

To configure an Ethernet interface without VLANs 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. Assign an IP address and mask.
   host1(config-if)#ip address 192.6.129.5 255.255.255.0
3. Specify PPPoE as the encapsulation method on the interface.
   host1(config-subif)#encapsulation pppoe

   This command creates the static PPPoE major interface.

4. Assign a profile to the PPPoE major interface.
   host1(config-subif)#pppoe profile pppoeProfile3

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

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