Before You Configure PPPoE

Configuring PPPoE over ATM

384
Before you attempt to configure a PPPoE interface, configure the physical interface over
which PPPoE traffic will flow. The procedures described in this chapter assume that a
physical interface has been configured.
This section provides an example of a common PPPoE over ATM configuration.
See the following resources for additional information:
"Configuring ATM" on page 3—Provides detailed information about ATM technology
and line interface module capabilities.
"Configuring Bridged Ethernet" on page 443—Provides configuration information about
Bridged Ethernet, which allows multiple upper-layer interface types (IP and PPPoE)
to be simultaneously multiplexed over the same interface.
"Configuring Dynamic Interfaces" on page 511—Provides detailed information about
configuring ATM to support dynamic interfaces.
Configuring Upper-Layer Protocols over Static Ethernet Interfaces on page 151
To configure PPPoE over ATM:
Configure a physical interface.
1.
host1(config)#interface atm 0/1
Configure the ATM 1483 subinterface.
2.
host1(config-if)#interface atm 0/1.20
Configure a PVC by specifying the vcd (virtual circuit descriptor), the vpi (virtual path
3.
identifier), the vci (virtual channel identifier), and the encapsulation type.
host1(config-if)#atm pvc 10 22 100 aal5snap
Select PPPoE as the encapsulation method.
4.
host1(config-subif)#encapsulation pppoe
Do one of the following to configure the maximum number of PPPoE sessions
5.
(subinterfaces) supported on the interface:
Configure the maximum number of PPPoE sessions on a per-interface basis.
host1(config-if)#pppoe sessions 128
Configure the maximum number of PPPoE sessions on a per-subscriber basis by
overriding the current PPPoE maximum session value with the PPPoE maximum
session value returned by the RADIUS server in the Max-Clients-Per-Interface
vendor-specific attribute (VSA) [26-143] in Access-Accept messages.
host1(config-if)#pppoe max-session-vsa override
Create a PPPoE subinterface.
