RFC 1483 / RFC 1490 Link Protocols
The Link Protocol RFC 1483 is a multiprotocol encapsulation method over ATM and is used by ATM routers.
RFC 1490 is a multiprotocol encapsulation method over Frame Relay and is used by Frame Relay routers.
RFC 1483 and RFC 1490 combined with the IP, IPX, or Bridging Network Protocols share the same configuration
characteristics, except for the connection identifiers: VPI/VCI numbers are used for RFC 1483 and a DLCI
number is used for RFC 1490.
Collect the information as described in the appropriate section. This data will be later used to configure your
router using the Command Line Interface (see
Configuration Tables,
Chapter 3).

VPI and VCI Numbers (for RFC 1483)
The VPI and VCI numbers apply to ATM routers only.
Your router may have been preconfigured with VPI/VCI numbers. If not, you will have to obtain these
numbers from your Network Service Provider and then configure them.
If you are connecting to multiple remote sites, you will need to obtain additional VPI and VCI numbers
from your Network Service Provider and/or Network Access Provider. These numbers identify the
remote destination and must, therefore, be unique for each remote.
DLCI (for RFC 1490)
The DLCI number applies to Frame Relay routers only.
Your Network Service Provider or your Network Access Provider will provide you with a DLCI (Data
Link Connection Identifier). The DLCI is an address identifying your connection.
DNS Internet Account Information (optional)
This information is obtained from the Network Service Provider
.
Consult with you Network Service Provider to find out if you need to enter the following information:
DNS Server Address
DNS Second Server Address
DNS Domain Name
IP Routing Entries
