Applying a Virtual Template Interface to a BBA Group
A BBA group is a template used to control connections. Cisco IOS Release 12.2(25)SX does not support
the configuration of broadband aggregation (BBA) groups using RADIUS. You must configure BBA
groups manually.
To apply a virtual template interface to a BBA group for Point-to-Point Protocol over Ethernet (PPPoE)
over IEEE
802.1Q VLAN, 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.
Configuration Example for Applying a Virtual Template Interface to a BBA Group
Example 4-16 shows how to create a BBA group named vpn1 and apply the virtual template named
VirtualTemplate 1 to the group. In the example, the BBA group configuration limits the number of
sessions per VC to 5 and specifies that a maximum of 10 PPPoE sessions can be terminated on the
interface or subinterface to which the BBA group is attached.
Example 4-16 Applying a Virtual Template Interface to a BBA Group
Router(config)# bba-group pppoe vpn1
Router(config-bba)# VirtualTemplate 1
Router(config-bba)# sessions per-vc limit 5
Router(config-bba)# sessions per-mac limit 10
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 configure multiple
BBA groups.
global is the default BBA group used for PPPoE connections
when a BBA group name is not specified.
Step 2
Router(config-bba)# virtual-template
template-number
Applies the virtual template interface you specify to the BBA
group. The router uses the virtual template interface to clone
virtual access interfaces (VAIs).
template-number is a number that identifies the virtual
template and is used to clone virtual-access interfaces.
