Configuring PPPoE on ATM PVCs Using a Different MAC Address
To change the way PPPoE selects a MAC address when PPPoE and RBE are configured on two separate
PVCs on the same DSL line, enter the following commands beginning in global configuration mode:
Note Use the pppoe mac-address command in VPDN group configuration mode. The
Cisco 10000 series router applies the command to all PPPoEoA sessions brought up after you issue the
command. MAC address usage does not change until you explicitly configure it using the pppoe
mac-address command. The router limits the change to PPPoE sessions on ATM interfaces only and
does not apply it to other interfaces on which PPPoE operates (such as Ethernet, Ethernet VLAN and
DOCSIS interfaces).
Configuring PPPoE over Ethernet Virtual Connections and Applying Virtual Templates
To configure PPPoE over Ethernet, perform the following configuration tasks:
• Configuring a Virtual Template Interface, page 3-17
• Configuring PPPoE over Ethernet in a BBA Group, page 3-21
Command Purpose
Step 1 Router(config)# vpdn-group pppoe-term Specifies the VPDN group to be used to establish PPPoE
sessions on a PVC.
Step 2 Router(config-vpdn)# accept-dialin Configures the L2TP access concentrator (LAC) to accept
PPPoE sessions from a client and creates an accept-dialin VPDN
subgroup.
Step 3 Router(config-vpdn-acc-in)# protocol pppoe Configures a static map for an ATM PVC.
Step 4 Router(config-vpdn-acc-in)# exit Exits accept-dialin configuration mode and returns to VPDN
configuration mode.
Step 5 Router(config-vpdn)# pppoe mac-address
{autoselect | mac-address}
Changes the way PPPoE selects a MAC address.
The autoselect option always chooses a “MAC plus 7” address
and no other address. For example, it chooses the ATM interface
MAC address, interface MAC address plus 1, plus 2, plus 3, plus
4, plus 5, or plus 6).
Use the mac-address option to enter an explicit MAC address
value.
