Configure the Fast Ethernet WAN Interfaces
In this scenario, the PPPoE client (your Cisco router) communicates over a 10/100 Mbps-Ethernet
interface on both the inside and the outside.
Perform these steps to configure the Fast Ethernet WAN interfaces, starting in global configuration
mode:
Command or Action Purpose
Step 1
vpdn enable
Example:
Router(config)# vpdn enable
Router(config)#
Enables VPDN on the router.
Step 2
vpdn-group name

Router(config)# vpdn-group 1
Router(config-vpdn)#
Creates and associates a VPDN group with a
customer or VPDN profile.
Step 3
request-dialin
Example:
Router(config-vpdn)# request-dialin
Router(config-vpdn-req-in)#
Creates a request-dialin VPDN subgroup,
indicating the dialing direction, and initiates the
tunnel.
Step 4
protocol {l2tp | pppoe}
Example:
Router(config-vpdn-req-in)# protocol pppoe
Router(config-vpdn-req-in)#
Specifies the type of sessions the VPDN subgroup
can establish.
Step 5
exit
Example:
Router(config-vpdn-req-in)# exit
Router(config-vpdn)#
Exits request-dialin VPDN group configuration.
Step 6

Example:
Router(config-vpdn)# exit
Router(config)#
