Figure12-1 Scenario 1: CTC and ONS 15454 SDH Nodes on the Same Subnet
12.2.2 Scenario 2: CTC and ONS 15454 SDH Nodes Connected to a Router
In Scenario 2 the CTC computer resides on a subnet (192.168.1.0) and attach es to LAN A (Figure 12-2).
The ONS 15454 SDH nodes 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
example shown in Figure 12-2, a DHCP server is not available.
