Chapter 1 Basic Router Configuration

Configure WAN Interfaces

The Cisco 1811 and Cisco 1812 routers each have two Fast Ethernet interfaces for WAN connection.
The Cisco 1801, Cisco 1802, and Cisco 1803 routers each have one ATM interface for WAN
connection.
Based on the router model you have, configure the WAN interface(s) using one of the following
procedures:
•
•

Configure the Fast Ethernet WAN Interface

This procedure applies only to the Cisco 1811 and Cisco 1812 router models. Perform these steps to
configure the Fast Ethernet interfaces, beginning in global configuration mode.
Command
Step 1 interface type number
Example:
Router(config)#interface fastethernet 0
Router(config-int)#
Step 2 ip address ip-address mask
Example:
Router(config-int)# ip address 192.1.12.2
255.255.255.0
Router(config-int)#
Step 3
no shutdown
Example:
Router(config-int)# no shutdown
Router(config-int)#
Step 4 exit
Example:
Router(config-int)# exit
Router(config)#
Repeat these steps for the other Fast Ethernet WAN interface if desired.
