LLC2 support in the FRX8000 includes the following scenarios, some of which are
diagrammed in Figure 11-1
Connection between a LAN-attached host/workstation and SNA devices, via
SDLC-to-LLC2 and LLC2-to-SDLC conversion, over a frame relay or X.25
network (example 1), or frame relay PVC (example 4).
Connection between LAN-attached workstations, over a frame relay or X.25
network (example 2), or a frame relay PVC (example 3).
Connection between workstations attached to different LANs on the same
FRX8000.
A virtual LAN ID is normally assigned by a system administrator. The ID is used
internally by the FRX8000 to identify a virtual bridge that connects the LLC2 function
to LAN interfaces. If LLC2 will run in a node, this ID must be configured in the Node
Defaults file (
