Problem
No route to network.
Solution
Check the routing table to see if a route exists to the network
where the interface is located. If no route exists, see
“Troubleshooting
Routing Problems”
on page 97.
Problem
Attached device does not have proper default route or routing
information.
Solution
If a local computer is unable to ping through an attached gateway,
the computer might contain either an invalid default route or invalid routing
information.
If you are using default routes from a computer, ensure that the local interface
is the default route for that computer.
Problem
The ARP table has old information.
Solution
If the ARP table has an old or invalid entry for the device
associated with the IP address you are attempting to ping, use Network
Voyager to delete the invalid entry.
For information about how to access Network Voyager and the related
reference materials, see
“Using Nokia Network Voyager”
on page 43.
To delete the invalid entry
1.
Click Config.
2.
Click ARP in the Interfaces section.
3.
Click Display or Remove Dynamic ARP Entries.
4.
Click Delete for the entry you want to delete.
5.
Click Apply.
