Figure 4-6 Scenario 5: Static Route With Multiple Lan Destinations - Cisco ONS 15327 User Documentation

ONS 15327 IP Addressing Scenarios
The destination and subnet mask entries control access to the ONS 15327s:
• 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.
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.
