ONS 15454 IP Addressing Scenarios
Figure4-5 Scenario 5: Static route with one CTC computer used as a destination
The destination and subnet mask entries control access to the ONS 15454s:
•If a single CTC computer is connected to router, enter the complete CTC “host route” IP address as
the destination with a subnet mask of 255.255.255.255.
•If CTC computers on a subnet are connected to router, enter the destination subnet (in this example,
192.168.1.0) and a subnet mask of 255.255.255.0.
•If all CTC computers are connected to router, enter a destination of 0.0.0.0 and a subnet mask of
0.0.0.0. Figure 4-6 shows an example.
The IP address of router interface B is entered as the next hop, and the cost (number of hops from source
to destination) is 2.
