Consider an organization with three departments: Sales, Accounting, and Engineering. Each department's computers are on its own separate network. In addition, the company itself has a connection to the Internet via its ISP (Internet Service Provider). So, its network diagram may look like the following:
A typical provisioning of the interfaces on the router may be:
|
Interface Description |
Speed |
Connection to |
|---|---|---|
|
Ethernet0 |
10 Mbps |
Sales |
|
Ethernet1 |
10 Mbps |
Accounting |
|
FastEthernet |
100 Mbps |
Engineering |
|
Serial1/0 |
512 Kbps |
ISP |
That is:
Another example is the case of the Internet Service Provider itself. It too has a router, which directs traffic from an Internet backbone to its many customers:
A typical router provisioning may be:
|
Interface Description |
Speed |
Connection to |
|---|---|---|
|
ATM2/0.1 |
512 Kbps |
Customer1 |
|
ATM2/0.2 |
384 Kbps |
Customer2 |
|
ATM2/0.3 |
384 Kbps |
Customer3 |
|
Serial2 |
544 Mbps |
Internet backbone |
A final example is the operation of the PI Universal Data Server/Data Archive receiving data from different areas of a plant, each with its own PI data collection interface program:
A typical router provisioning may be:
|
Interface Description |
Speed |
Connection to |
|---|---|---|
|
Ethernet1 |
10 Mbps |
Foxboro area of the plant |
|
Ethernet2 |
10 Mbps |
Honeywell area of the plant |
|
Ethernet3 |
10 Mbps |
Yokogawa area of the plant |
|
Ethernet0 |
10 Mbps |
PI Server area of the plant |
