    If ONS 15454s are connected to Open Shortest Path First (OSPF) networks, ONS 15454 

network information is automatically communicated across multiple LANs and WANs. 

 
    The ONS 15454 proxy server controls the visibility and accessibility between CTC 

computers and ONS 15454 element nodes. 

 

 
ONS 15454 IP addressing generally has seven common scenarios or configurations. Use the 
following scenarios as building blocks for more complex network configurations. 
 

 
Figure 8-1 shows a basic ONS 15454 LAN configuration.  The ONS 15454 nodes and CTC 
computer reside on the same subnet.  All ONS 15454 nodes connect to LAN A, and all ONS 
15454 nodes have DCC connections. 
 

 

 

 

 
In Figure 8-2 the CTC computer resides on subnet 192.168.1.0 and attaches to LAN A.  The ONS 
15454 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 DHCP 
(Dynamic Host Configuration Protocol), the default gateway and IP address are assigned 
automatically.  In the Figure 8-2 example, a DHCP server is not available.
