<h1 class="topictitle1">Create the interface to enable proxy ARP</h1>
|
||
|
|
<div><div class="section"><p>Before you create the TCP/IP interfaces, you need to decide how
|
||
|
|
you want to connect your virtual Ethernet to a physical LAN. To allow your
|
||
|
|
logical partitions to communicate with systems on an external LAN, you need
|
||
|
|
to enable the TCP/IP traffic to travel between the virtual Ethernet and the
|
||
|
|
external LAN. There are three methods for connecting the virtual and external
|
||
|
|
networks: Proxy ARP, network address translation (NAT), and TCP/IP routing.
|
||
|
|
This scenario uses the Proxy ARP method. For more information about all three
|
||
|
|
methods of connecting this network traffic, see TCP/IP techniques connecting
|
||
|
|
virtual Ethernet to external LANs.</p>
|
||
|
|
<p>To create the TCP/IP interface to
|
||
|
|
enable proxy ARP, complete these steps: </p>
|
||
|
|
<ol><li>Obtain a contiguous block of IP addresses that are routable by your network.
|
||
|
|
<p>Because you have a total of four logical partitions in this virtual Ethernet,
|
||
|
|
you need a block of eight addresses. The fourth segment of the first IP address
|
||
|
|
in the block must be divisible by eight. The first and last IP addresses of
|
||
|
|
this block are the subnet and broadcast IP addresses and are unusable. The
|
||
|
|
second address can be used for a virtual TCP/IP interface on logical partition
|
||
|
|
A, and the third, fourth, and fifth addresses can be used for the TCP/IP connections
|
||
|
|
on each of the other logical partitions. For this scenario, the IP address
|
||
|
|
block is 10.1.1.72 through 10.1.1.79 with a subnet mask of 255.255.255.248.</p>
|
||
|
|
<p>You
|
||
|
|
also need a single IP address for your external TCP/IP address. This IP address
|
||
|
|
should not belong to your block of contiguous addresses, but it must be within
|
||
|
|
the same original subnet mask of 255.255.255.0.</p>
|
||
|
|
</li>
|
||
|
|
<li>Create an i5/OS™ TCP/IP interface for logical partition
|
||
|
|
A. This interface is known as the external, proxy ARP IP interface. <div class="p">To
|
||
|
|
create the interface, follow these steps: <ol type="a"><li>At the command line on partition A, type <samp class="codeph">CFGTCP</samp>, and
|
||
|
|
press Enter to see the Configure TCP/IP display.</li>
|
||
|
|
<li>Select option 1 (Work with TCP/IP Interfaces), and press Enter.</li>
|
||
|
|
<li>Select option 1 (Add), and press Enter to see the Add TCP/IP Interface
|
||
|
|
(ADDTCPIFC) display.</li>
|
||
|
|
<li>For the Internet address prompt, type <samp class="codeph">10.1.1.15</samp>.</li>
|
||
|
|
<li>For the Line description prompt, type the name of your
|
||
|
|
line description, such as ETHLINE.</li>
|
||
|
|
<li>For the Subnet mask prompt, type <samp class="codeph">255.255.255.0</samp>.</li>
|
||
|
|
</ol>
|
||
|
|
</div>
|
||
|
|
</li>
|
||
|
|
<li>Start the interface. On the Work with TCP/IP Interfaces display, select
|
||
|
|
option 9 (Start) by the interface you want to start.</li>
