Introduction

This document describes how to set up a Frame Relay connection to an ISP using a Compatible Systems Internet Access Router.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

This document is not restricted to specific software and hardware versions.

Conventions

Refer to the Cisco Technical Tips Conventions for more information on document conventions.

Configure

In this section, you are presented with the information to configure the features described in this document.

Note: Use the Command Lookup Tool ( registered customers only) to obtain more information on the commands used in this section.

Your Internet Service Provider (ISP) will assign Class C network or subnet numbers for your network and the Wide Area Network (WAN) ports from a group of network numbers assigned to them by the Internet Information Center (InterNIC) .

Note: All IP addresses in this example are for demonstrational purposes only and have been borrowed from the private address space reserved by the Internet Assigned Numbers Authority (IANA) .

Connecting your Local Area Network (LAN)

Your ISP has provided you with the following information:

• Customer Network Address: 192.168.200.0

• Customer Subnet Mask: 255.255.255.0

• Customer WAN port Address: 192.168.100.1

• Customer WAN port Subnet Mask: 255.255.255.0

• Customer DLCI Number: 68

• ISP Gateway Address: 192.168.100.2

ur LAN is connected to the ISP by a PVC (Permanent Virtual Circuit) through a "Frame Relay cloud" using two Communication Service Units (CSUs). The ISP has assigned you a complete Class C network with 254 node addresses to your LAN. We have chosen to use the first address (192.168.200.1) for the router's Ethernet IP address. Other hosts on your network will select from the remaining addresses (2 to 254) for their IP addresses and define the default gateway in their TCP/IP setup as the router's Ethernet IP address.

Your ISP assigned you a WAN port address, an ISP Gateway address, and a Data Link Connection Identifier (DLCI). Your DLCI number is mapped across the PVC to the ISP's Gateway address.
