information; Low means that the RIP information takes precedence over the static route.

■If the static route conflicts with a connection profile, the connection profile will always take precedence.

■To make sure that the static route is known only to the Netopia 4553, select Advertise Route Via RIP and toggle it to No. To allow other RIP-capable routers to know about the static route, select Advertise Route Via RIP and toggle it to Yes. When Advertise Route Via RIP is toggled to Yes, a new item called RIP 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 32 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.

Modifying a static route

To modify a static route, in the Static Routes screen select Display/Change Static Route to display a table of static routes.

Select a static route from the table and go to the Change Static Route screen. The parameters in this screen are the same as the ones in the Add Static Route screen (see “Adding a static route” on page 8-70).

Deleting a static route

To delete a static route, in the Static Routes screen select Delete Static Route 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 Escape.

Rules of static route installation

The Netopia 4553 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 an IP address in the range of IP addresses being distributed by DHCP.

■The static route’s Next Gateway IP Address is determined to be unreachable by the Netopia 4553.

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

■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 that 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.
