ViewStation Local Route Command

HDSware version 3.2 includes a local route command to let you add or delete routes from the ViewStation's route table. Use the route command in the Console Window. The route command is:

route [add|delete] [net|host] <destination gateway> [metric]

This command lets you add or delete routes or networks and hosts for the ViewStation. The "metric" argument must be included for adding a route; it is the number of hops to the final destination.

The ViewStation supports as many as four IP addresses. Its communication is limited to those IP addresses and the local subnets appropriate for them. The concept of a "route" simply tells the ViewStation how to get to a different IP address. This specified route gives a path for any packets with IP addresses not on the ViewSta tion's known communications paths.

For a ViewStation (IP = 128.91.6.11) follow these examples:
To add a route for a host on a different net, say 198.89.6.3:
route add host 198.89.6.3 128.91.2.5 2
This command tells the ViewStation that any packets addressed to "198.89.6.3" should be sent to address 128.91.2.5, which is the "destination gateway" computer which will then forward the packets as needed.

The command to add a route for a network is:
route add net 128.92.0.0 128.91.2.5 2
which routes all packets addressed to the 128.92 network through the 128.91.2.5 gateway.

To delete the route for a network, the command is:
route delete net 128.92.0.0 128.91.2.5

ViewStation Local Ping Command
The ViewStation has a local "ping" command included with HDSware version 3.2 or higher. Refer also to the PING man pages.

The ping command is useful in determining if a host is reachable from the View Station. It is an easy way to see if the gateways and routes are working. Simply type the ping command with the host you want to reach:

ping<hostname>

The return message reports if the host is alive and reachable or not.
