Chapter 3 Configuring PPP over Ethernet with NAT
Configure the Fast Ethernet WAN Interfaces
Perform these steps to configure the Fast Ethernet WAN interfaces, starting in global configuration
mode:
Command Purpose
Step 1
interface type number
Example:
Router(config)#interface fastethernet 0
Router(config-if)#
Enters interface configuration mode for a
Fast
Ethernet WAN interface.
The Cisco 1800 integrated services routers have
two Fast Ethernet WAN interfaces. You can use
these steps to configure one or both of them.
Step 2
pppoe-client dial-pool-number number
Example:
Router(config-if)# pppoe-client
dial-pool-number 1
Router(config-if)#
Configures the PPPoE client and specifies the
dialer interface to use for cloning.
Step 3
no shutdown
Example:
Router(config-if)# no shutdown
Router(config-if)#
Enables the Fast Ethernet interface and the
configuration changes just made to it.
Step 4
exit
Example:
Router(config-if)# exit
Router(config)#
Exits configuration mode for the Fast Ethernet
interface and returns to global configuration
mode.
