Introduction
Frame Relay is a high-speed datalink communications technology that is used in hundreds of networks
throughout the world to connect LAN, SNA, Internet, and voice applications. Within the network, Frame
Relay uses a simple form of packet switching that provides high throughput and reliability.
The access server offers IP-in-Frame Relay, or RFC-1490 Multi-protocol encapsulation. Because the access
server has a built-on router, the access server can route IP traffic to multiple locations over multiple virtual
channels. Using a T1 or E1 WAN link the access server can function as a network-to-network interface (NNI)
switch or as a User-to-Network Interface (UNI). Most applications will be as an UNI.
A Frame Relay network consists of endpoints (the access server), frame relay access equipment (bridges, rout-
ers, hosts, frame relay access devices) and network devices (switches, network routers, T1/E1 multiplexers).
The most popular application is to use the access server as a PoP-in-a-box with a Frame Relay IP connection to
the Internet backbone.
Configuring a Frame Relay link
The most common configuration is setting up the access server as a DCE and connecting to a provider’s Frame
switch via a T1 /E1 line. In this application, the access server will establish a point-to-point link via one or
more DLCI’s or virtual channels. Each DLCI is a pipe with an associated far-end IP address. You may then
modify the access server’s routing table and enter in routes to use the Frame Relay link as the next-hop.
A Frame Relay link is configured as follows:
•
Configuring the WAN link for Frame Relay
•
Selecting the correct Frame Link configuration parameters (LMI)
•
Assigning an IP address to the DLCI.
•
Assigning next-hop routes to the new DLCI.
Line Configuration
The first stage in setting up a Frame Relay WAN link is configuring a T1 or E1 line for Frame Relay service.
1. Click on
T1/E1 Link
under the
Configuration Menu
to to display the T1/E1 Link Activity main window
2. Verify which port the T1/E1 cable is connected into on the access server—that port number corresponds
to the Link: x (where x is the same number as the port number) portion of the T1/E1 Link Activity main
window (see figure 71 on page 220). Click on Configuration in the appropriate Link: x section (for exam-
ple, if the T1/E1 cable was connected to port 2, you would click on
Configuration
in the
Link: 2
section).
Note
If your access server’s ports are labeled A and B. Port A corresponds to
Link: 1 and port B with Link: 2.
