Chapter 1 Basic Router Configuration
Configuring Basic Parameters
AAL5SNAP—This can be either routed RFC 1483 or bridged RFC 1483. For routed RFC 1483,
the service provider must provide you with a static IP address. For bridged RFC 1483, you may
use DHCP to obtain your IP address, or you may obtain a static IP address from your service
provider.
AAL5MUX PPP—With this type of encapsulation, you need to determine the PPP-related
configuration items.
• If you plan to connect over an ADSL or G.SHDSL line:
–
Order the appropriate line from your public telephone service provider.
For ADSL lines—Ensure that the ADSL signaling type is DMT (also called ANSI T1.413) or
DMT Issue 2.
For G.SHDSL lines—Verify that the G.SHDSL line conforms to the ITU G.991.2 standard and
supports Annex A (North America) or Annex B (Europe).
Once you have collected the appropriate information, you can perform a full configuration on
your router, beginning with the tasks in the
“Configuring Basic Parameters” section.
Configuring Basic Parameters
To configure the router, perform one or more of these tasks:
• Configure Global Parameters
• Configure Fast Ethernet LAN Interfaces
• Configure WAN Interfaces
• Configuring a Loopback Interface
• Configuring Command-Line Access to the Router
A configuration example is presented with each task to show the network configuration following
completion of that task.
