DNS Internet Account Information (optional)
The Domain Name Service (DNS) maps host names to IP addresses. DNS is
performed by Domain Name Servers. The router can get DNS information
automatically. Or, you can choose to configure DNS manually. Consult with your
Network Service Provider to determine if you need to enter the following information:
• DNS server address
• DNS second server address
• DNS domain name
RFC 1483/RFC 1490 Link Protocols
The link protocols RFC 1483 and RFC 1490 are multiprotocol encapsulation methods.
RFC 1483 is used over ATM; RFC 1490 is used over Frame Relay.
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.
IP Routing Network Protocol
To configure the IP network protocol and RFC 1483 or RFC 1490 as the link protocol,
you need the following information.
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, get these numbers from your Network
Service Provider.
If you are connecting to multiple remote sites, get additional VPI and VCI numbers
from your Network Service Provider. These numbers identify the remote destination
and must be unique for each remote.
DLCI number (for RFC 1490)
The DLCI (Data Link Connection Identifier) number applies to Frame Relay routers
only. Get your DLCI from your service provider.
DNS Internet Account Information (optional)
Consult with your Network Service Provider to determine if you need to enter the
following information:
• DNS server address
• DNS second server address
• DNS domain name
