router (Node D) that needs to connect to three other branch nodes (Nodes A to C).
The solid line denotes a permanent SVC. The dotted lines denote On Demand SVCs.
In Figure 2-12, Node D has a LANView of the WAN. The WAN is really a logical
LAN with an IP network level address of 10.0.0.0. Node D has one IP Router
Interface with address 10.0.0.4, which can reach any of the branches (Nodes A to C)
via three SVCs tied to the same Router Interface (for example, Interface #5). This
example shows that a LANView can be a mix of Permanent and On Demand SVCs.
Without LANView functionality, this same network would require Node D to have
three IP Router Interfaces, each with a different IP network level address. With
LANView, the same three connections use only one IP network level address.
