Chapter 6 Configuring PPPoE over Ethernet and IEEE 802.1Q VLAN
PPPoE over IEEE 802.1Q VLANs
• Configuring PPPoE in a VPDN Group, page 6-8
• Configuring PPPoE in a BBA Group, page 6-9
The following sections describe how to perform these configuration tasks. For more information, see the
“Configuring Broadband Access: PPP and Routed Bridge Encapsulation” chapter in the Cisco IOS
Wide-Area Networking Configuration Guide.
Configuring a Virtual Template Interface
Configure a virtual template interface before you configure PPPoE on an IEEE 802.1Q VLAN interface.
The virtual template interface is a logical entity that is applied dynamically as needed to a serial
interface. To configure a virtual template interface, see the
“Configuring a Virtual Template Interface”
section on page 3-17 .
Creating an Ethernet 802.1Q Encapsulated Subinterface and Enabling PPPoE
To create an Ethernet 802.1Q encapsulated subinterface and enable PPPoE on it, enter the following
commands beginning in global configuration mode:
Configuring PPPoE in a VPDN Group
To configure a VPDN group for PPPoE and link it to the appropriate virtual template interface, enter the
following commands beginning in global configuration mode:
Command Purpose
Step 1 Router(config)# interface GigabitEthernet
slot/module/port.subinterface-number
Creates a Gigabit Ethernet subinterface and enters subinterface
configuration mode.
Step 2 Router(config-subif)# encapsulation dot1q
vlan-id
Enables IEEE 802.1Q encapsulation on a specified subinterface
in VLANs.
Step 3 Router(config-subif)# pppoe enable Enables PPPoE and allows PPPoE sessions to be created through
the specified subinterface.
Step 4 Router(config-subif)# pppoe max-sessions
number
Specifies the maximum number of PPPoE sessions that can be
terminated on this router from all interfaces.
Command Purpose
Step 1 Router(config)# vpdn enable Enables VPDN configuration on the router.
Step 2 Router(config)# vpdn-group name Associates a VPDN group to a customer or VPDN profile.
