Assign a VLAN ID for the subinterface.
host1(config-if)# vlan id 400
■
Assign a VLAN ID and the optional unique MAC address for the subinterface.
host1(config-if)# vlan id 400 mac-address 0090.1a01.1234
5.
Create an IP interface on the same VLAN as the PPPoE interface.
host1(config-if)# ip address 164.10.6.71 255.255.255.0
6.
Specify PPPoE as the encapsulation method on the interface.
host1(config-if)# pppoe
7.
Create a PPPoE subinterface.

through 9 using unique numbering.
To configure additional IP interfaces over the VLAN major interface:
1.
Create a new VLAN subinterface by adding a unique subinterface number to the
interface identification command.
host1(config-if)# interface fastEthernet 4/1.2
2.
Assign a VLAN ID for the subinterface.
host1(config-if)# vlan id 401
3.
