Chapter 3 Configuring PPP over Ethernet with NAT
Configure the Fast Ethernet WAN Interfaces
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.
Note The Cisco 1800 series integrated services fixed-configuration routers have a hardware limitation on the
Fast Ethernet ports FE0 and FE1. In half-duplex mode, when traffic reaches or exceeds 100% capacity
(equal to or greater than 5 Mbps in each direction), the interface experiences excessive collisions and
resets every second. To avoid this problem, you must limit the traffic capacity to less than 100%.
Step 3
request-dialin
Example:
Router(config-vpdn-grp)# request-dialin
Router(config-vpdn-grp)#
Creates a request-dialin VPDN subgroup,
indicating the dialing direction, and initiates the
tunnel.
Step 4 initiate to ip ip-address
Example:
Router(config-vpdn-grp)# initiate to
192.168.1.1
Router(config-vpdn-grp)#
Specifies the address to which requests are
tunneled.
For details about this command and additional
parameters that can be set, see the
Cisco IOS Dial
Technologies Command Reference .
Step 5 protocol { l2f | l2tp | pppoe | any }
Example:
Router(config-vpdn-grp)# protocol pppoe
Router(config-vpdn-grp)#
Specifies the type of sessions the VPDN subgroup
can establish.
Step 6
exit
Example:
Router(config-vpdn-grp)# exit
Router(config-vpdn)#
Exits VPDN group configuration.
Step 7 exit
Example:
Router(config-vpdn)# exit
Router(config)#
Exits VPDN configuration, returning to global
configuration mode.
