the VLAN subinterfaces.

Configuring Higher-Level Protocols over VLANs

This section provides examples for configuring IP, PPPoE, and MPLS interfaces over
VLAN subinterfaces configured on bridged Ethernet. These procedures assume that
you have already configured one or more VLAN subinterfaces over the bridged
Ethernet interface to carry the higher-level protocols.

Configuring IP over VLAN

Configuring VLANs over Bridged Ethernet
Create a VLAN subinterface to carry the higher-level protocols by adding a
subinterface number to the interface identification command.
host1(config-subif)#interface atm 4/0.101.1
Assign a VLAN ID for the subinterface.
host1(config-subif)#vlan id 10
(Optional) Configure additional VLAN subinterfaces by repeating Steps 4 and 5,
using unique values.
host1(config-subif)#interface atm 4/0.101.2
host1(config-subif)#vlan id 11
Follow the steps in "Configuring VLAN Subinterfaces over Bridged Ethernet" on
page 403 to configure the VLAN subinterface.
Assign an IP address and mask to the VLAN subinterface.
host1(config-subif)#ip address 10.1.1.1 255.255.255.0
Follow the steps in "Configuring VLAN Subinterfaces over Bridged Ethernet" on
page 403 to configure the VLAN subinterface.
Create a PPPoE major interface on the VLAN subinterface.
host1(config-subif)#pppoe
Exit the subinterface context.
host1(config-subif)#exit
Create a PPPoE subinterface by adding a subinterface number to the interface
identification command.
