2.1.3 - IPX Routing
The IOLINK-520 & IOLINK-PRO are pre-configured to operate as an IPX router. When
installed in an IPX network, the IOLINK router will learn the IPX network numbers from
connected networks. It will then route the IPX frames to the appropriate destination IPX
network.
The IPX routing scenario may consist of one of the two following configurations. The first
configuration consists of Novell servers located on each of the LAN segments to be
connected. The second configuration consists of Novell servers located on only one of the
LAN segments to be connected. The IOLINK router IPX router will need to be
configured differently in the second configuration with Novell servers located on only one
of the LAN segments.
2.1.3.1 - Novell Servers in Both Locations
An Ethernet IPX router is used to intelligently route Novell IPX LAN traffic to another
network. The networks may be connected across a WAN link (illustrated below) or two
LANs connected to a dual LAN IOLINK-520.
Figure 2 -3 IPX Routed Local Area Networks (Servers on both sides)
IPX routers forward IPX frames based upon their IPX destination address and an internal
routing table. The router maintains the internal routing table with the network IPX
addresses and the remote partner IPX routers associated with those networks. When an
IPX frame is received, the destination IPX address is examined and looked up in the routing
tables. Once the destination IPX address is found in the routing tables, the IPX router
sends the IPX frame to the appropriate remote IPX network.
When both LAN segments contain Novell servers, the IPX network numbers are learned
automatically; simply ensure that IPX routing is enabled on the router for both networks.
When two IPX LAN segments with Novell servers on each segment are to be
connected via IPX routing, you must ensure that the IPX network numbers on each
of the Novell servers is unique. If the IPX network numbers are the same, IPX
routing will not operate.
