Netopia R3100 manual Modifying a static route, Deleting a static route

IP Setup and Network Address Translation 11-15

Metric appears below Advertise Route Via RIP.

With RIP Metric you set the number of routers, from 1 to 15, between the sending router and the destination router. The maximum number of routers on a packet’s route is 15. Setting RIP Metric to 1 means that a route can involve 15 routers, while setting it to 15 means a route can only involve one router.

■Select ADD STATIC ROUTE NOW to save the new static route, or select CANCEL to discard it and return to the Static Routes screen.

■Up to 16 static routes can be created, but one is always reserved for the default gateway, which is configured using either Easy Setup or the IP Setup screen in System Configuration.

To delete a static route, select Delete Static Route in the Static Routes screen to display a table of static routes. Select a static route from the table and press Return to delete it. To exit the table without deleting the selected static route, press the Escape key.

Rules of static route installation

The Netopia R3100 applies certain rules before installing enabled static routes in the IP routing table. An enabled static route will not be installed in the IP routing table if any of the following conditions are true:

■The static route’s Next Gateway IP Address matches the IP address used by a connection profile or the Netopia R3100’s Ethernet port.

■The static route’s Next Gateway IP Address matches an IP address in the range of IP addresses being distributed by MacIP or DHCP.

■The static route’s Next Gateway IP Address is determined to be unreachable by the Netopia R3100.

■The static route’s route information conflicts with a connection profile’s route information.

■The connection profile associated with the static route is set for dial-in connections only, and there is no incoming call connected to that connection profile.

■The connection profile associated with the static route has a disabled dial-on-demand setting, and there is no current connection using that connection profile.

A static route is already installed in the IP routing table will be removed if any of the conditions listed above become true for that static route. However, an enabled static route is automatically reinstalled once the conditions listed above are no longer true for that static route.
