2-14
The Vanguard provides two types of interconnection of LANs over a WAN,
LANView and WANView. This section provides a brief description of each and
example functional diagrams.
The following table describes WANView and LANView.

Figure 2-7 and Figure 2-6 show the difference in the internal data connections
between a LANview (Group LCONs) and traditional WANview (point-to-point
LCONs). With LANView, three different LCONs are mapped to the same Router
Interface. With a WANview, each LCON (that is, each virtual circuit) is tied to a
different Router Interface. For WANView, each Router Interface must be assigned a
different IP Network (or Subnetwork) address.
Description
The most common mechanism of routing between
two Vanguard routers over a WAN link with a virtual
circuit configured as a point-to-point LAN connection
(LCON). The LCON is associated with a unique
router interface on each end. The LCON is considered
to be a network with only two hosts and is assigned its
own, unique subnetwork number.
Grouped LCONs are multiple virtual circuits
associated with the same router interface.
Conceptually, all of the WAN-attached nodes are
considered to be on a virtual LAN. All WAN
interfaces are assigned different host addresses on the
same network number.
