IP Scenario 5: Static Route With One CTC Computer Used as a Destination
LAN A
CTC Workstation
IP Address 192.168.1.100
Subnet Mask 255.255.255.0
Default Gateway = 192.168.1.1
Host Routes = N/A
ONS 15454 #2
IP Address 192.168.3.20
Subnet Mask 255.255.255.0
Default Router = N/A
Static Routes = N/A
The destination and subnet mask entries control access to the ONS 15454s:
•
•
•
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. You must manually add static routes between the CTC computers on LAN A, B, and
C and Nodes 2 and 3 because these nodes are on different subnets.

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 13-7
shows an example.
Destination 192.168.4.0
Mask 255.255.255.0
Next Hop 192.168.2.10
Destination 192.168.1.0
Mask 255.255.255.0
Next Hop 192.168.2.1
Cost = 2
ONS 15454 #3
IP Address 192.168.4.30
Subnet Mask 255.255.255.0
Default Router = N/A
Static Routes = N/A
