Configure the Virtual Private Dialup Network Group Number
PPPoE
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:
•
•
NAT
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.
Configuration Tasks
Perform the following tasks to configure this network scenario:

Configure the Virtual Private Dialup Network Group Number
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

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.
