EXAMPLE 2: IP ROUTING NETWORK—EXTERNAL ROUTERS
Example 2 (see Figure 6-7) depicts an IP network with external routers. An
ATLAS 800
PLUS
with a frame relay upgrade is located at the central site. A
TSU 100e with an external router connected to an Nx56/64 module is locat-
ed at each of two remote sites, and an FSU with an external router is located
at the third remote site. At the central site, ATLAS terminates a full T1 frame
relay connection from the XYZ service provider and switches the PVCs to
the external router. To re-create this example, follow the process discussed
below.
