If the route still does not appear, contact your distributor or
reseller for assistance.
Telnet Fails
1 If Telnet to a router fails, check that the IP address you used
matches the one assigned to the router. Check that RIP is
configured correctly (steps 4 and 5 above). Check that the IP
Telnet server is enabled on each router, using the command:
SHOW IP
If the Telnet server is disabled, enable the Telnet server with
the command:
ENABLE IP TELNETSERVER
2 If Telnet into a host on the remote LAN fails, but works into
the remote router, check the IP address you are using is correct.
Check that both routers are gateways, not servers by typing:
SHOW IP
The “IP Packet Forwarding” field in the output should be set to
“Enabled”. The host’s TCP/IP software should be configured to
use the Head Office router as its gateway. Refer to the
documentation for the host TCP/IP software for more
information about configuring a gateway.
3 Contact your distributor or reseller for assistance.
You will see the login screen for the Remote Office router. To
connect from the Remote Office router to the Head Office
router, on the Remote Office router use the command:
TELNET 172.16.8.33
Note: We have used the Ethernet address in this example but you
can Telnet to any of the remote router’s assigned IP addresses.
Save the Configuration
Save the new dynamic configuration as a script, by entering
the command:
CREATE CONFIG=IPCONF.SCP
TROUBLESHOOTING IP CONFIGURATIONS
No Route Exists to the Remote Router
1 Wait for at least one minute to ensure that a RIP update has
been received.
2 Repeat steps 4 and 5 above. Check that the PPP link is
OPENED for both LCP and IP by entering the command:
SHOW PPP
The display should look like that shown above.
3 Try restarting the IP routing software (a warm restart), by
entering the command:
RESET IP
Example output from the SHOW IP
ROUTE command for a basic TCP/IP
network.
