Static Route tab

To improve the static route management in previous releases, the IP Static Routing Table Manager feature was added to this release, allowing users to change static routes directly. This new 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 will automatically be 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 must be done through the Static Routing Table, while static route deletion can be done through either the Static Routing Table or the System Routing Table.

Note: Only active static routes will be 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 will be 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 with 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 will become inactive and disappear 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 will become active and will be added to the System Routing Table. However, static routes, whether enabled or disabled, can be 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. Choose Routing > IP > Static Route.

The IP Routing IP dialog box opens with the Static Route tab displayed.

2. Click Insert.

The Insert Static Route dialog box is displayed.

NOTE: THIS SCREEN MAY CHANGE, PER REVIEW TEAM ON 4/19.

3. In the Dest box, type the IP address.
4. In the Mask box, type the mask.
5. In the NextHop box, select the router through which the specified route is accessible.
6. In the Metric box, type the HopOrMetric value.
7. Click Insert.

The route appears in the routing table.
