Configuring RIP on the <strong>Sidewinder</strong> <strong>G2</strong><br />

Defining route filter<br />

information<br />

D-14 Configuring Dynamic Routing with RIP<br />

The route filter entries highlight one <strong>of</strong> the major limitations <strong>of</strong> routed<br />

and the RIP protocol. routed recognizes only the standard class A, class<br />

B, and class C IP network masks (255.0.0.0, 255.255.0.0, and<br />

255.255.255.0). The <strong>Sidewinder</strong> <strong>G2</strong> route filter entries allow more flexible<br />

network masks for forward compatibility.<br />

8. Click the Save icon in the toolbar to save your routed configuration<br />

changes.<br />

The Route Filter Information window appears if you click the New or<br />

Modify button from the Routed Configuration window. The Route<br />

Filter Information window allows you to create a new or modify an<br />

existing route filter. Follow the steps below.<br />

1. In the Type field, select the type <strong>of</strong> route being defined: host (host route)<br />

or net (network route).<br />

2. In the Address field, specify either the IP address <strong>of</strong> the host for host<br />

routes, or the network portion <strong>of</strong> the IP address for network routes.<br />

3. (Network route only) If you selected net in step 1, specify which portion<br />

<strong>of</strong> the address parameter should be considered valid in the Netmask<br />

field. There are two possible ways to enter the network mask. One is to<br />

use the "dotted decimal" form, such as 255.255.255.0 for class C<br />

networks. The other is to use the hexadecimal representation, which<br />

would be ffffff00 for class C.<br />

4. In the Direction drop-down list, select which direction routed should<br />

apply for this filter. This option provides you with a lot <strong>of</strong> flexibility in<br />

determining what routing information you accept and provide.<br />

Important: Be careful about what routes you advertise to external users and<br />

about accepting routes from those same external users.<br />

Inbound—Specifies routed will not accept this route from the<br />

network. However, it WILL include this route in an advertisement if<br />

you have selected the Advertise option.<br />

Outbound—Specifies that routed will accept this route from the<br />

network. but NOT advertise this route regardless <strong>of</strong> the advertise<br />

option setting.<br />

Both—Specifies routed to ignore this route.<br />

5. Click Add to add the route filter to the list and exit the window.
