Configuring PPPoE over VLAN

To configure PPPoE over VLAN over an Ethernet interface:

1. Specify a Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet port.

   host1(config)#interface fastEthernet 4/1

2. Specify VLAN as the encapsulation method.

   host1(config-if)#encapsulation vlan

   The VLAN major interface is added.

3. Create a VLAN subinterface by adding a subinterface number to the interface identification command.

   host1(config-if)#interface fastEthernet 4/1.1

4. Do one of the following:
   • Assign a VLAN ID for the subinterface.

     host1(config-if)#vlan id 201

   • Assign a VLAN ID and the optional unique MAC address for the subinterface.

     host1(config-if)#vlan id 201 mac-address 0090.1a01.1234

5. Specify PPPoE as the encapsulation method on the interface.

   host1(config-if)#pppoe

6. Create a PPPoE subinterface.

   host1(config-if)#pppoe subinterface fastEthernet 4/1.1.1

7. Specify PPP as the encapsulation method on the interface.

   host1(config-if)#encapsulation ppp

8. Assign an IP address and mask.

   host1(config-if)#ip address 192.6.129.5 255.255.255.0

9. (Optional) Configure additional VLAN subinterfaces by completing Steps 3 through 8.

Figure 15 illustrates the PPPoE/VLAN/Fast Ethernet stacking, showing two separate VLAN subinterfaces. One VLAN subinterface has two PPPoE subinterfaces, and one VLAN subinterface has one PPPoE subinterface.
