It is important to understand that in a bridged 

 

network the addressing structure for both IP and IPX 

 

relates to a single network. If the units in 

 

 

 

were bridges and not routers, then an IP node on 

 

LAN A could, for example, have an address 

 

140.56.10.0, the node on LAN B an address 

 

140.56.10.2, and the node on LAN C, an address of 

 

140.56.10.3. All the nodes, therefore, are able to share 

 

the same Class B network address, regardless of their 

 

location on the bridged network.

 

However, if there were NetWare nodes throughout the 

 

three bridged sites, they would also share the same 

 

IPX network number. If each of the bridged LANs 

 

supported a network server, each with its own unique 

 

network number, and an IPX address is 

 

misconfigured, the NetWare network server consoles 

 

will report the message ‘Router Configuration Error – 

 

Router XXXXX claims that LAN is XX-XX-XX-XX’. (The 

 

router it refers to is in fact the network server).
