DLSw+ over Frame Relay Configuration Example
Frame Relay support extends the DLSw+ capabilities to include Frame Relay in direct mode. Frame
Relay support includes permanent virtual circuit capability. DLSw+ runs over Frame Relay with or
without local acknowledgement. It supports the Token Ring-to-Token Ring connections similar to FST
and other direct data link controls. Figure 138 illustrates a DLSw+ configuration over Frame Relay with
RIF Passthrough.
Figure 138 DLSw+ over Frame Relay
The following configuration examples are based on Figure 139. The Token Rings in the illustration are
in Ring 2.
