If the destination node exists in any of the <Other networks 1 to 5> noted above, the ET-LAN unit
communicates with the node through routers 1 to 5. In this case, the network (sub-network) address of
the destination node will match the “Network (sub-network) address of the destination node will match
the “Network (sub-network) address” of one of the five routers registered in the routing information
setting area. (Refer to the IP addresses for the five routers “Router 1 to 5” in the illustration, and to the
network addresses for the five networks “Network 1 to 5”.)
-
In any other case, communication with the destination node is carried out through the default router
(gateway) (if the destination node is located in networks A to C in the illustration).
Key Point:
1) The network (sub-network) addresses of the five routers (“Router 1 to 5” on the source network are
registered, along with the IP addresses. The “network (sub-network) addresses” are the network (sub-
network) addresses of the adjacent networks connected through the routers.
2) An IP address is registered for only one default router (gateway). The default router (gateway) may be
the same as one of the five routers “Router 1 to 5” specified in step 1), or it may be different.
