SRB over Frame Relay Configuration Example

SRB over Frame Relay Configuration Example

Figure 59 illustrates a network with the following characteristics:

•Virtual Ring Number of Router A = 100

•Virtual Ring Number of FRAD B = 200

•Virtual Ring Number of FRAD C = 300

•DLCI number for PVC between Router A and FRAD B = 30

•DLCI number for PVC between Router A and FRAD C = 31

In this example, we configure a new option, conserve-ring, on the source-bridgeinterface configuration command. When this option is configured, the SRB software does not add the ring number associated with the Frame Relay PVC (the partner’s virtual ring) to outbound explorer frames. This option is permitted for Frame Relay subinterfaces only.

The router configures the partner FRAD’s virtual ring number as the ring number for the PVC.

This approach does not require a separate ring number per DLCI. The router configures the partner FRAD’s virtual ring number as the ring number for the PVC.

FRAD B would configure its virtual ring as 200 and the ring for the PVC as 100. FRAD C would configure its virtual ring as 300 and the ring for the PVC as 100.
