Configuring WAN Connections

Configuring Frame Relay connections

Pipeline User’s Guide Preliminary January 30, 1998 1-25

network, and the DLCI may change as frames are passed through multiple

switches.

Note:

You need at least one Frame Relay profile and Connection profile to

define a logical link to the Frame Relay network.

To configure a Frame Relay connection, you must perform the following tasks:

• Make sure that nailed channels are available for the link to the Frame Relay

switch.

• Configure a Frame Relay profile that uses those channels to connect to the

Frame Relay (FR) switch.

• Obtain the DLCIs you need from the Frame Relay administrator (at the

telephone company, or your network administrator).

Each connection requires its own DLCI.

• Obtain the routing/bridging information for the remote network.

• Make sure that the Answer profile enables FR encapsulation.

• Configure the Frame Relay connection in a Connection profile.

• Configure the routing or bridging setup in the Pipeline and across the WAN

connection.

Note:

This section focuses on configuring Frame Relay connections. It assumes

that the Answer profile has been set up to enable such connections. (For a

discussion about enabling connections, see “The Answer profile” on page 1-7.)

Configuring bridging and routing is discussed in subsequent chapters.

Example of options used to configure logical links

A Connection profile defines a logical link to an end-point reached through a

Frame Relay switch. The Pipeline supports Frame Relay “Gateway” mode. A

Frame Relay gateway connection is a bridging or routing link between the

Pipeline and a remote network via a Frame Relay switch. When the Pipeline

receives IP packets destined for that network, it encapsulates the packets in

Frame Relay (as specified in RFC 1490) and forwards the data stream with the

specified DLCI to the Frame Relay switch. The Frame Relay switch uses the

DLCI to route the frames to the right destination.

Figure 1-2 shows a Pipeline with three gateway connections to customer premise

equipment (CPE) at remote sites across the Frame Relay network. Gateway
