19.2.2 Scenario 2: CTC and ONS 15454s Connected to a Router

In Scenario 2, the CTC computer resides on a subnet (192.168.1.0) and attaches to LAN A
The ONS 15454s reside on a different subnet (192.168.2.0) and attach to LAN B. A router connects LAN
A to LAN B. The IP address of router interface A is set to LAN A (192.168.1.1), and the IP address of
router interface B is set to LAN B (192.168.2.1). The routers each have a subnet mask of 255.255.255.0.
On the CTC computer, the default gateway is set to router interface A. If the LAN uses DHCP (Dynamic
Host Configuration Protocol), the default gateway and IP address are assigned automatically. In the
