8.2.5 Scenario 5: Using Static Routes to Connect to LANs

Static routes are used for two purposes:

•To connect ONS 15310-MA SDH nodes to CTC sessions on one subnet that are connected by a router to ONS 15310-MA SDH nodes 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 15310-MA SDH nodes residing on the same subnet.

In Figure 8-6, one CTC residing on subnet 192.168.1.0 connects to a router through interface A. (The router is not set up with OSPF.) ONS 15310-MA SDH nodes 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.
