Static Routes tab

The IP Static Routing Table Manager allows you to change static routes directly. The Static Route table is separate from the System Routing Table, which the router uses to make forwarding decisions. Although the tables are separate, entries in the Static Routing Table Manager are automatically reflected in the System Routing Table if the next hop address in the static route is reachable and the static route is enabled.

The table is indexed by three attributes (Destination Network, Destination Mask, and Next Hop), and the maximum number of entries is 500. Static route insertion is done through the Static Routing Table, while static route deletion is done through either the Static Routing Table or the System Routing Table.

Note: Only active static routes are seen in the System Routing Table. A static route is active only if the route is enabled and the next hop address is reachable; that is, there is a valid ARP entry for the next hop.

You can enter multiple routes (multiple default routes, for example) that have different costs, and the lowest-cost route that is reachable is used in the routing table. Note that if you enter multiple next hops for the same route with the same cost, the software does not replace the existing route. If you enter the same route with the same cost and a different next hop, the first route is used. However, should that first route become unreachable, the second route (with a different next hop) is activated with no loss of connectivity.

An active static route becomes inactive and disappears from the System Routing Table if the route is disabled or the next hop is not reachable. If the next hop of an enabled but inactive static route becomes reachable, the route becomes active and is added to the System Routing Table. However, static routes, whether enabled or disabled, are found in the Static Routing Table.

Static routes provide a way to create routes to destination IP address prefixes manually.

To create a static IP route:

1. From the Device Manager window menu bar, choose IP Routing > IP.

The IP dialog box opens with the Globals tab displayed.

2. Click Static Routes.

The Static Routes tab opens.

3. Click Insert.

The Insert Static Routes dialog box opens.
