Configuring an ADSL WAN Interface Card on Cisco 1700 Series Routers
OL-3317-03
Configuring the ADSL Interface
Router (config-if) dsl operating-mode mode
Caution This command is for testing or lab environments only. Using a mode other auto for the DSL operating
mode can lead to unpredictable behavior on the ADSL line.
Step 8 Configure routing protocols on the interface. (You must have previously enabled these protocols as part
of global configuration.) In this example, IP, AppleTalk, and IPX are being configured on the ADSL
interface:
Router(config-if)# ip address 1.10.16.16 255.255.0.0
Router(config-if)# appletalk static cable-range 5-5
Router(config-if)# appletalk zone ZZ
Router(config-if)# ipx network B004
Step 9 Configure a PVC on the interface. (You must have the VPI/VCI number from the service provider
before you configure this.)
Router (config-if)# pvc 0/33
Router (config-if-atm-vc)# protocol ip 1.10.16.16 broadcast
Router (config-if-atm-vc)# vbr-rt 160 160 1
Router (config-if-atm-vc)# encapsulation aal5snap
Step 10 To configure another interface, enter the exit command to return to the Router(config)# prompt.
Repeat Step 6 through Step 9 of this procedure to configure the next interface.
Step 11 When you finish configuring interfaces, exit configuration mode. Return to the enable prompt by
pressing Ctrl-Z. To see the current operating configuration, including any changes you just made, enter
the show running-config command:
Router# show running-config
To see the configuration currently stored in NVRAM, enter the show startup-config command:
Router# show startup-config
Step 12 The results of the show running-config and show startup-config commands differ if you have made
changes to the configuration but have not yet written them to NVRAM. To write your changes to
NVRAM and make them permanent, enter the copy running-config startup-config command:
Router# copy running-config startup-config
Building configuration. . .
[OK]
Router#
The router is now configured to boot in the new configuration.
AutoInstall
The AutoInstall process is designed to configure the router automatically after it connects to your WAN.
For AutoInstall to work properly, a TCP/IP host on your network must be configured to provide the
configuration files. The TCP/IP host can reside anywhere on the network if the following two conditions
are met:
• The host must be on the remote side of the router’s synchronous serial connection to the WAN.
• User Datagram Protocol (UDP) broadcasts to and from the router and the TCP/IP host must be
enabled.
