12.2.3 IPX Routing
Here you will find some problems that could crop up with IPX routing together
with suggestions on how they can be solved.
➤
Use the Setup Tool or MMI to check if you have entered the right license.
➤
Use the Setup Tool to check in IPX if the entry under Internal Network
Number is unique in the LAN.
A server exists in a remote LAN (LAN-LAN connection over ISDN),
but is "invisible" for clients in the local LAN.
The server could be invisible for clients because SAP packets are not received
from the server:
➤
Check the entries in Update Time and Age Multiplier in WAN P
ARTNER
➧
E
DIT
➧
IPX. The settings must be compatible with the settings on the
servers in X4000 ’s LAN.
➤
Check if a router between them filters out the SAP packets.
➤
Check with isdnlogin if an ISDN connection can be made between client
and server.
➤
Check if you have made the correct entries in Local IPX NetNumber and
Encapsulation under
CM-100BT, F
AST
E
THERNET
and if the server can
receive them.
When the client tries to reach a server in a remote network over a
PPP connection, he must wait a long time and the connection is
possibly terminated.
In some cases, the local router erroneously tells the client that a server can be
reached.
➤
Check if the server has crashed and that the aging interval has not yet
expired. If necessary, change the setting of Send RIP/SAP Updates under
WAN P
ARTNER
➧
E
DIT
➧
IPX.
➤
Check if the server and the router in the remote network are simultaneously
inactive (e.g. because of a power cut). Briefly set the WAN interface of the
corresponding WAN partner with the command
ifconfig
to
down and
