13.2 13.2.4 IP Scenario 4: Default Gateway on a CTC Computer
In Figure 13-4, Node 1 announces to Node 2 and 3 that it can reach the CTC host. Similarly, Node 3
announces that it can reach the ONS 152xx. The ONS 152xx is shown as an example; any network
element (NE) can be set up as an additional host.

13.2.4 IP Scenario 4: Default Gateway on a CTC Computer
IP Scenario 4 is similar to IP Scenario 3, but Nodes 2 and 3 reside on different subnets, 192.168.2.0 and
192.168.3.0, respectively (Figure 13-5). 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.
