STEP FOUR
The Encapsulation parameters for Frame Relay are less straight-forward. Many of them are based on
decisions that cannot be shown in a diagram. Fortunately, the choices made here will mostly effect the
performance of the link, rather than whether it works or not. Fill in the parameters appropriate for your system,
consulting chapter 8 of the Installation Manual for more information if necessary.

for the example. The router on the
sending end must be using the same header
type (NLPID or SNAP) as the router on the
receiving end.
LMI ANSI for the example. This must also be
the same as the router on the receiving end.
T391 Ten seconds, the interval between the LMI
Status Enquiry messages.
N391 Six.
N392 Three.
N393 Four. This value must be larger than N392.
CIR 90 percent. 100 minus this number is the
percentage of total bandwidth that may be
discarded if the network is congested.
Bandwidth Reservation Inactive. Traffic control will not be covered

FIGURE 4.13 FRAME RELAY ENCAPSULATION MENU PARAMETERS
At the end of the parameter list shown above, the DLCI menu appears. Choosing Add DLCI will lead to the
parameters shown in Figure 4.14. The <ESC> key used at any time during the Frame Relay encapsulation
parameter list will also bring up the DLCI menu. A DLCI entry must be created for every remote Frame Relay
network to be contacted. In the example, only one is shown.
