13.2.1 IP Scenario 1: CTC and ONS 15454s on Same Subnet
IP Scenario 1 shows a basic ONS 15454 LAN configuration (Figure 13-1). The ONS 15454s and CTC
computer reside on the same subnet. All ONS 15454s connect to LAN A, and all ONS 15454s have DCC
connections.

13.2.2 IP Scenario 2: CTC and ONS 15454 Nodes Connected to a Router
In IP Scenario 2 the CTC computer resides on a subnet (192.168.1.0) and attaches to LAN A
(Figure 13-2). 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).
On the CTC computer, the default gateway is set to router interface A. If the LAN uses Dynamic Host
Configuration Protocol (DHCP), the default gateway and IP address are assigned automatically. In the
Figure 13-2 example, a DHCP server is not available.
