Scenario 5: Static Route with One CTC Computer Used as a Destination
The destination and subnet mask entries control access to the ONS 15600 SDHs:
•
If a single CTC computer will be 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 router, enter a destination of 0.0.0.0 and a subnet mask of
0.0.0.0.
shows an example. In this figure, the IP address of router interface B is entered as the next
hop (the next router that a packet traverses to reach its destination), and the cost (number of hops from
source to destination) is 2.
