router is not set up with OSPF). ONS 15454s residing on different subnets are connected through Node
1 to the router through interface B. Because Nodes 2 and 3 are on different subnets, proxy ARP does not
enable Node 1 as a gateway. To connect to CTC computers on LAN A, a static route is created on
Node 1.

To connect ONS 15454s to CTC sessions on one subnet connected by a router to ONS 15454s
residing on another subnet. (These static routes are not needed if OSPF is enabled. Scenario 6 shows
an OSPF example.)
To enable multiple CTC sessions among ONS 15454s residing on the same subnet.
