Cisco ONS 15454 SDH Reference Manual, R5.0

Chapter 12 CTC Network Connectivity
12.2.4 Scenario 4: Default Gateway on CTC Computer
In Figure 12-4, ONS 15454 SDH #1 announces to ONS 15454 SDH #2 and #3 that it can reach the CTC
host. Similarly, ONS 15454 SDH #3 announces that it can reach the ONS 152xx. The ONS 152xx is
shown as an example; any network element can be set up as an additional host.
Figure 12-4 Scenario 3: Using Proxy ARP with Static Routing
12.2.4 Scenario 4: Default Gateway on CTC Computer
Scenario 4 is similar to Scenario 3, but Nodes 2 and 3 reside on different subnets, 192.168.2.0 and
192.168.3.0, respectively (Figure 12-5). Node 1 and the CTC computer are on subnet 192.168.1.0. Proxy
ARP is not used because the network includes different subnets. In order for the CTC computer to
communicate with Nodes 2 and 3, Node 1 is entered as the default gateway on the CTC computer.
