15.2.5 Scenario 5: Using Static Routes to Connect to LANs
Figure 15-6 Scenario 5: Static Route With One CTC Computer Used as a Destination (ANSI and ETSI)
The destination and subnet mask entries control access to the ONS 15454s:
• If a single CTC computer is connected to a 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 a 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 a router, enter a destination of 0.0.0.0 and a subnet mask of
0.0.0.0. Figure 15-7 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.
