Chapter 6 Configuring PPPoE over Ethernet and IEEE 802.1Q VLAN
PPPoE over Ethernet
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:
Note You cannot simultaneously configure a 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.
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 for each VC that uses the group.
Step 6 Router(config-bba-group)# exit Returns to global configuration mode.
Step 7 Router(config)# interface type number Specifies the interface to which you want to attach the BBA
group and enters interface configuration mode.
Step 8 Router(config-if)# encapsulation dot1q vlan-id Enables IEEE 802.1Q encapsulation of traffic on a specified
subinterface in a VLAN. Specify the VLAN identifier.
Step 9 Router(config-if)# protocol pppoe group
group-name
Attaches the BBA group to the VLAN.
