<h1 class="topictitle1">Routes</h1>
|
||
|
|
<div><p>You need to verify that the appropriate routes are configured.</p>
|
||
|
|
<p>Your server needs routes to send packets to other servers or hosts. The
|
||
|
|
route determines the path that a packet takes to its destination.</p>
|
||
|
|
<div class="p">If you are trying to Ping an interface address and do not receive a reply,
|
||
|
|
you should verify that your routes are configured and available. To communicate
|
||
|
|
between a local and remote network, whether you are using IPv4 or IPv6 connectivity,
|
||
|
|
you should have at least these two types of routes configured on the server: <ul><li>A direct route (*DIRECT) allows packets to travel between interfaces on
|
||
|
|
the local network. It is automatically configured and activated by the server
|
||
|
|
for each interface.</li>
|
||
|
|
<li>A default route (*DFTROUTE) allows packets to travel to hosts that are
|
||
|
|
not directly connected to your network. It provides a path for the packets
|
||
|
|
to take. A default route identifies a specific node as a next hop to which
|
||
|
|
the packets travel and then continue their trip to their final destination
|
||
|
|
on a different network. The packets take the default route whenever there
|
||
|
|
is no other (more specific) route matching the destination IP address.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<p>Keep in mind that routes are unidirectional. Just because a packet from
|
||
|
|
a client can get to your system does not mean that your system can send a
|
||
|
|
packet to the client.</p>
|
||
|
|
<p>Verify that the appropriate IPv4 or IPv6 routes are configured on your
|
||
|
|
server.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">IPv4 routes</h4><div class="p">To display information about the IPv4
|
||
|
|
routes on your server, follow these steps:<ol><li>Type <kbd class="userinput">NETSTAT</kbd> or <kbd class="userinput">WRKTCPSTS</kbd> on
|
||
|
|
the command line to display the Work with Network Status menu, and then select
|
||
|
|
option 2 on this menu.</li>
|
||
|
|
<li>Select option 5 (Display details) for details about a specific route.</li>
|
||
|
|
<li>If you do not have a default route configured, you should configure it
|
||
|
|
now. To configure a default route, follow these steps:<ol type="a"><li>At the command line, type <samp class="codeph">CFGTCP</samp> to access the Configure
|
||
|
|
TCP/IP menu.</li>
|
||
|
|
<li>Select option 2 (Work with TCP/IP Routes).</li>
|
||
|
|
<li>Select option 1 (Add) to go to the Add TCP/IP Route (ADDTCPRTE) display.</li>
|
||
|
|
<li>For the <em>Route destination</em> prompt, specify <samp class="codeph">*DFTROUTE</samp>.</li>
|
||
|
|
<li>For the <em>Subnet mask</em> prompt, specify <samp class="codeph">*NONE</samp>.</li>
|
||
|
|
<li>For the <em>Next hop</em> prompt, specify the appropriate IP address.</li>
|
||
|
|
</ol>
|
||
|
|
</li>
|
||
|
|
</ol>
|
||
|
|
</div>
|
||
|
|
<p>As an alternative, you can configure a default route using the <span class="uicontrol">New
|
||
|
|
IPv4 Route</span> wizard in iSeries™ Navigator. See the route information
|
||
|
|
for iSeries Navigator
|
||
|
|
for more information.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">IPv6 routes</h4><p>To display information about the IPv6
|
||
|
|
routes on your server, follow these steps:</p>
|
||
|
|
<ol><li>Type <kbd class="userinput">NETSTAT</kbd> or <kbd class="userinput">WRKTCPSTS</kbd> on
|
||
|
|
the command line to display the Work with Network Status menu, and then select
|
||
|
|
option 5 on the menu.</li>
|
||
|
|
<li>Select option 5 (Display details) for details about a specific route.</li>
|
||
|
|
</ol>
|
||
|
|
<p>For IPv6, the Internet Protocol automatically configures default routes
|
||
|
|
for each interface on the server. However, if you prefer, you can use the <span class="uicontrol">New
|
||
|
|
IPv6 Route</span> wizard in iSeries Navigator to create new routes
|
||
|
|
yourself. See the route information for iSeries Navigator for more information.</p>
