- <H2>Routing Gateway Configuration</H2>
- <P>
- With dynamic routing, it is often useful to add a static route
- into the kernel routing table, or to force the routing daemon to
- ignore route updates for a network. These measures provide greater
- control over the path that packets take to known destinations. For
- example, you might create a default route to your Internet service
- provider, forcing packets for an unknown remote host to always be
- sent to the ISP router.
- </P>
- <P>
- The IRIX kernel compares the destination address in each network packet
- that it receives to the addresses of the local network interfaces. If
- the address does not match any interface address, it searches the kernel
- routing table for the best matching address. If it finds a matching
- <I>Host route</I> (an exact address match) or a matching <I>Network route</I>,
- it sends the packet to the gateway that is designated in the matching
- routing table entry. If there is no other route, the packet is forwarded
- to the gateway for the default route (host route for 0.0.0.0) if a default
- host route is listed in the table.
- <P>
- Use the Gateway Configuration form to change the following parameters:
- </P>
- <P>
- <STRONG>Enable dynamic routing</STRONG> This selection turns routing on
- and off for this system. Select Yes to turn on dynamic routing and No to turn it
- off. Typically, any system connected to a company intranet that
- contains more than one network should have dynamic routing turned
- on.
- </P>
- (Default value: Yes)
- <P>
- Note: This is identical to the <I>Enable dynamic routing</I> selection on the
- Dynamic Routing form. You can change the setting from either form (your
- selection is automatically applied to the Dynamic Routing form to update it).
- </P>
- <P>
- <STRONG>Add New Gateway</STRONG> This field contains the packet destination
- address of a gateway that you want to add. Enter the address and select the
- <VAR>Add New Gateway</VAR> button to display the Add New Gateway form.
- Complete the entry fields on this form and click the <VAR>Ok</VAR> button
- to add the gateway. Enter the packet destination address in dotted decimal
- (such as 1.2.3.4 for a host route or 1.2.0.0 for a network route) or
- hexadecimal (such as 0x01020304 or 0x01020000) notation.
- </P>
- (Default value: none)
- <P>
- <STRONG>Edit Selected Gateway</STRONG> This list contains the addresses of
- active gateways. Select a destination address from the list and select
- the <VAR>Edit Selected Gateway</VAR> button to display the Edit Gateway
- form and make your changes. When you finish, click the <VAR>Ok</VAR> button
- to put the changes in effect.
- </P>
- (Default value: none)
- <P>
- <STRONG>Delete Selected Gateway</STRONG> Select a destination address from
- the list and click the <VAR>Delete Selected Gateway</VAR> button to remove
- the address from the list. Then click the <VAR>Ok</VAR> button to put the
- changes in effect.
- </P>
- (Default value: none)
- <P>
- <STRONG>IP address of destination:</STRONG> This information field contains
- the currently selected destination address in the Add or Edit Gateway form.
- This field is not editable.
- </P>
- <P>
- <STRONG>IP address of gateway system:</STRONG> This is the address of
- a system closer to the destination that knows how to reach the
- destination address. Enter a fully qualified host address in dotted
- decimal (such as 1.2.3.4) or hexadecimal (such as 0x01020304) notation.
- </P>
- (Default value: none)
- <P>
- <STRONG>Type of destination address:</STRONG> This field specifies
- the type of the destination address. If the address is a host address
- (such as 1.2.3.4) or the default destination 0.0.0.0, then select
- <VAR>host</VAR>. If the address is a network address (such as 1.2.3.0),
- then select <VAR>net</VAR>.
- </P>
- (Default value: none)
- <P>
- <STRONG>Mode of network gateway:</STRONG> If this gateway is running a
- routing daemon, select <VAR>active</VAR>; this selection notifies the
- gateway that it should exchange routing information on the network. Select
- <VAR>passive</VAR> if the gateway should not exchange routing information.
- </P>
- (Default value: none)
- <P>
- <STRONG>Number of hops from route interface to destination:</STRONG>
- This is the number of systems between the Internet Gateway and the
- destination system, including the Gateway itself. A hop count of
- <EM>0</EM> means that the destination is the local host; a hop count
- of <EM>16</EM> is considered infinite and no packets will ever be
- forwarded there.
- </P>
- (Default value: 1)
