The PPPoE Client feature on the router provides PPPoE client support on Ethernet interfaces. A dialer 
interface must be used for cloning virtual access. Multiple PPPoE client sessions can be configured on 
an Ethernet interface, but each session must use a separate dialer interface and a separate dialer pool. 

A PPPoE session is initiated on the client side by the Cisco 1800 series router. An established PPPoE 
client session can be terminated in one of two ways:

By entering the clear vpdn tunnel pppoe command. The PPPoE client session terminates, and the 
PPPoE client immediately tries to reestablish the session. This also occurs if the session has a 
timeout.

By entering the no pppoe-client dial-pool number command to clear the session. The PPPoE client 
does not attempt to reestablish the session.

NAT (represented as the dashed line at the edge of the Cisco router) signifies two addressing domains 
and the inside source address. The source list defines how the packet travels through the network.

Perform the following tasks to configure this network scenario:

An example showing the results of these configuration tasks is shown in the section “

Configuring a virtual private dialup network (VPDN) enables multiple clients to communicate through 
the router by way of a single IP address. 

Complete the following steps to configure a VPDN, starting from the global configuration mode. See the 

 for details about entering this mode.

Router(config)# vpdn enable

Router(config-vpdn)# 

Enables VPDN on the router.

vpdn group name

Router(config-vpdn)# vpdn group 1

Router(config-vpdn-grp)# 

Creates and associates a VPDN group with a 
customer or VPDN profile.
