Figure 2-1. DLSw-Capable Routers on an IP Backbone
For Frame Relay networks, you must configure the DLSw router for source route
encapsulation to use SRB. When you enable DLSw on an interface that supports
source route encapsulation, the software displays a dialog box that asks you if you
want to use source route encapsulation. Select OK to configure the router to use
the Bay Networks proprietary SRB over Ethernet or Frame Relay using the RFC
1490 Bridging Standard. Select Cancel to configure the router to use the RFC
1490 Routing Standard. For Token Ring networks, source route encapsulation is
the default.
Figure 2-2 illustrates a sample DLSw and SRB network.
