Chapter 6 Configuring PPPoE over Ethernet and IEEE 802.1Q VLAN
PPPoE over IEEE 802.1Q VLANs
Note You cannot simultaneously configure a broadband aggregation (BBA) group for PPPoE and a VPDN
group for PPPoE. If you configure a BBA group and then you configure a VPDN group, the protocol
command in VPDN accept-dialin configuration mode does not include an option for PPPoE (for
example, you cannot specify the protocol pppoe command). Use the no bba-group pppoe command to
re-enable the pppoe option for the protocol command.
Configuring PPPoE in a BBA Group
Note Cisco IOS Release 12.2(15)BX does not support the configuration of BBA groups using RADIUS. You
must configure BBA groups manually.
To configure a broadband aggregation (BBA) group for PPPoE and to link it to the appropriate virtual
template interface, enter the following commands beginning in global configuration mode:
Step 3
Router(config-vpdn)# accept-dialin
Creates an accept dial-in VPDN group.
Step 4
Router(config-vpdn-acc-in)# protocol pppoe
Specifies the VPDN group to be used to establish
PPPoE
sessions.
Step 5
Router(config-vpdn-acc-in)# virtual-template
template-number
Specifies the virtual template interface to use to clone virtual
access interfaces (VAIs).
Step 6
Router(config-vpdn)# pppoe limit per-vlan
number
(Optional) Specifies the maximum number of PPPoE sessions
under each VLAN.
Step 7
Router(config-vpdn)# pppoe limit per-mac
per-mac-limit
(Optional) Specifies the maximum number of sessions per
MAC address for each PPPoE port that uses the group.
Step 8
Router(config-vpdn)# pppoe limit max-sessions
number
(Optional) Specifies the maximum number of PPPoE sessions
that can be terminated on this router from all interfaces.
Command Purpose
Command Purpose
Step 1
Router(config)# bba-group pppoe {name |
global}
Configures a BBA group to be used to establish PPPoE
sessions.
name identifies the BBA group. You can have multiple BBA
groups.
global is the default BBA group used for ATM connections
when a BBA group name is not specified.
Step 2
Router(config-bba-group)# virtual-template
template-number
Specifies the virtual template interface to use to clone virtual
access interfaces (VAIs).
Step 3
Router(config-bba-group)# sessions per-mac
limit per-MAC session limit
(Optional) Specifies the maximum number of sessions per
MAC address for each PPPoE port that uses the group.
Step 4
Router(config-bba-group)# sessions per-vlan
limit per-VLAN session limit
(Optional) Specifies the maximum number of PPPoE
sessions under each VLAN.
Step 5
Router(config-bba-group)# sessions per-vc
limit per-VC session limit
(Optional) Specifies the maximum number of PPPoE
sessions to be terminated on this router from all interfaces.
