4. Check route tables
To check the route tables on both routers, enter the command:
SHOW IPX ROUTE
Check for the presence of networks on the remote side of the wide area
network. If the remote network is missing from the route table on either
router, enter the command:
RESET IPX
which resets the IPX routing software and forces the routers to broadcast
their routing and service tables.

Using Trace Route for IP Traffic

You can use trace route to discover the route that packets pass between two
systems running the IP protocol. Trace route sends an initial UDP packets with
the Time To Live (TTL) field in the IP header set starting at 1. The TTL field is
increased by one for every subsequent packet sent until the destination is
reached. Each hop along the path between two systems responds with a TTL
exceeded packet and from this the path is determined.
To initiate a trace route, enter the command:
TRACE [[IPADDRESS=]ipadd] [MAXTTL=number] [MINTTL=number]
[NUMBER=number] [PORT=port-number] [SCREENOUTPUT={YES|NO}]
[SOURCE=ipadd] [TIMEOUT=number] [TOS=number]
Any parameters not specified use the defaults configured with a previous
invocation of the command:
SET TRACE [[IPADDRESS=]ipadd] [MAXTTL=number] [MINTTL=number]
[NUMBER=number] [PORT=port-number] [SCREENOUTPUT={YES|NO}]
[SOURCE=ipadd] [TIMEOUT=number] [TOS=number]
As each response packet is received a message is displayed on the terminal
device from which the command was entered and the details are recorded. To
display the default configuration and summary information, enter the
command:
