Configuration Tasks for RA to MPLS VPN
Configuring PPPoE over Ethernet in a BBA Group
Note Cisco IOS Release 12.2(15)BX does not support RADIUS configuration of BBA groups. 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:
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)# virtual-template
template-number
Specifies the virtual template interface to use to clone virtual
access interfaces (VAIs).
Step 3
Router(config-bba)# 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 4
Router(config-bba)# pppoe limit max-sessions
number
(Optional) Specifies the maximum number of PPPoE
sessions that can be terminated on this router from all
interfaces.
Step 5
Router(config-bba)# pppoe limit per-vc
per-vc-limit
(Optional) Specifies the maximum number of PPPoE
sessions for each VC that uses the group.
Step 6
Router(config-bba)# exit
Returns to global configuration mode.
Step 7
Router(config)# interface atm
slot/subslot/port.subinterface
Specifies the interface to which you want to attach the BBA
group.
Step 8
Router(config-if)# pvc [name] vpi/vci
Creates an ATM permanent virtual circuit (PVC) and enters
ATM PVC configuration mode.
(Optional) name specifies the name of the PVC or map. The
name can be up to 16 characters.
vpi/ specifies the ATM network VPI for the PVC that you
named. Valid values are from 0 to 255. If a value is not
specified, the vpi value is set to 0.
vci specifies the ATM network VCI for the PVC you named.
Valid values are from 0 to 1 less than the maximum value set
for this interface using the atm vc-per-vp command.
Note You cannot set both vpi and vci to 0; if one is 0, the
other cannot be 0.
Step 9
Router(config-if)# protocol pppoe group
group-name
Attaches the BBA group to the PVC.
