Figure 8-4 Scenario 3: Using Proxy ARP with Static Routing
8.2.4 Scenario 4: Default Gateway on CTC Computer

Scenario 4 is similar to Scenario 3, but ONS 15310-MA SDH Node 2 and Node 3 reside on different

subnets, 192.168.2.0 and 192.168.3.0, respectively (Figure 8-5). Node 1 and the CTC computer are on

subnet 192.168.1.0. Proxy ARP is not used because the network includes different subnets. For the CTC

computer to communicate with Nodes 2 and 3, Node 1 is entered as the default gateway on the CTC

computer.
