Figure 15 on page 175 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.
Figure 15: Example of PPPoE/VLAN/Fast Ethernet Stacking Configuration Procedure
Configuring MPLS over VLAN
To configure MPLS over VLAN over an Ethernet interface:
1.
host1(config-if)#pppoe subinterface fastEthernet 4/1.1.1
Specify PPP as the encapsulation method on the interface.
host1(config-if)#encapsulation ppp
Assign an IP address and mask.
host1(config-if)#ip address 192.6.129.5 255.255.255.0
(Optional) Configure additional VLAN subinterfaces by completing Steps 3 through
8.
Specify a Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet port.
host1(config)#interface fastEthernet 4/0
