Dynamic Routing

Figure 7-40

From the Dynamic Routing screen, shown on Figure 7-40, you can enable the Router to automatically adjust to physical changes in the network’s layout. The Router, using the RIP protocol, determines the network packets’ route based on the fewest number of hops between the source and the destination. The RIP pro- tocol regularly broadcasts routing information to other routers on the network. To set up Dynamic Routing:

1.Choose the correct Working Mode. Gateway Mode should be used if the Router is hosting your network’s connection to the Internet. Router Mode should be selected if the Router exists on a network with other routers. In Router Mode, any computer connected to the Router will not be able to con- nect to the Internet unless you have another router function as the Gateway.

2.Choose a Dynamic Routing path protocol for either transmission (TX) or reception (RX) of network data.

Click the Show Routing Table button to open a chart displaying how data is routed through your LAN.

When finished making your changes on this tab, click the Apply button fol- lowed by the Continue button to save these changes, or click the Cancel but- ton to undo your changes. For further help on this tab, click the Help button.

Static Routing

Figure 7-41

If the Router is connected to more than one network, it may be necessary to set up a static route between them. This can be done from the Static Routing screen, shown in Figure 7-41. A static route is a pre-determined pathway that network information must travel to reach a specific host or network. From the Static Routing tab, click the Show Routing Table button to view the current static routing configuration.

To create a static route entry:

1.Select a Static Route Entry from the drop-down list. The Router supports up to 20 static route entries.

To delete a Static Routing entry, select an entry, and click the Delete this entry button.
