		<description><![CDATA[<p style="text-align: justify">Buat yang lagi belajar <a href="http://www.baqare.com/index.php/category/networking"target="_parent"rel="external"title="network" >network</a>, ini satu lagi share info mengenai kolaborasi Layer 2 (Datalink) dan Layer 3 (Network) yg di applikasikan dalam sebuah Router. kebetu<a href="http://www.baqare.com/index.php/local-area-network-lan"target="_self"rel="external"title="LAN" >lan</a> router yg dipakai contoh adalah <a href="http://www.baqare.com/index.php/category/cisco"target="_self"rel="external"title="Cisco " >Cisco</a> Router 1841 dengan ditambah module card HWIC-4ESW.</p>
<p style="text-align: justify">Lagi-<a href="http://technorati.com/tag/2">2</a>x Packet Tracer4 yg akan mensimulasikan, so..gak perlu beli dulu cisco devicenya…mahal booo..:)<span id="more-<a href="http://technorati.com/tag/3">3</a>61"></span></p>
<p style="text-align: justify">Sedikit mengingatkan, secara default router 1841 hanya dilengkapi dengan 1 port console, 1 port Aux, dan <a href="http://technorati.com/tag/2">2</a> port FastEthernet. untuk module HWIC-4ESW harus kita tambahkan sendiri dengan cara &#8<a href="http://technorati.com/tag/2">2</a>20;drag-drop&#8221; pada module yg kosong. tentunya posisi power switch harus OFF terlebih dahulu (liat Gambar. 1, dan Gambar.2)</p>
<p style="text-align: justify"><span style="font-size:10pt">Gambar.1                    Gambar.2<br />
</span></p>
<p style="text-align: justify"><a href="C:\%5CDocuments and Settings%5CArif Phoenix%5CApplication Data%5CWindows Live Writer%5CPostSupportingFiles%5C2234f5d2-5601-496f-8a74-14afc2860be8%5Cimage2.png"><img src="http://localhost/baqare/wp-content/uploads/2009/06/062909_0806_mengenallay13.png" border="0" alt="" /></a><a href="C:\%5CDocuments and Settings%5CArif Phoenix%5CApplication Data%5CWindows Live Writer%5CPostSupportingFiles%5C2234f5d2-5601-496f-8a74-14afc2860be8%5Cimage5.png"><img src="http://localhost/baqare/wp-content/uploads/2009/06/062909_0806_mengenallay21.png" border="0" alt="" /></a><a href="C:\%5CDocuments and Settings%5CArif Phoenix%5CApplication Data%5CWindows Live Writer%5CPostSupportingFiles%5C2234f5d2-5601-496f-8a74-14afc2860be8%5Cimage11.png"><img src="http://localhost/baqare/wp-content/uploads/2009/06/062909_0806_mengenallay31.png" border="0" alt="" /></a><a href="C:\%5CDocuments and Settings%5CArif Phoenix%5CApplication Data%5CWindows Live Writer%5CPostSupportingFiles%5C2234f5d2-5601-496f-8a74-14afc2860be8%5Cimage11.png"><img src="http://localhost/baqare/wp-content/uploads/2009/06/062909_0806_mengenallay41.png" border="0" alt="" /></a></p>
<p><span style="font-size:12pt">Sebagai contoh kasus, berikut ini Topology yg akan kita gunakan<br />
</span></p>
<p><img src="http://localhost/baqare/wp-content/uploads/2009/06/062909_0806_mengenallay51.png" alt="" /><span style="font-family:Times New Ro<a href="http://www.baqare.com/index.php/metro-area-network-man"target="_top"rel="external"title="MAN" >man</a>; font-size:12pt&#8221;><br />
</span></p>
<p><strong>High Light pada topology ini adalah :</strong></p>
<p>1. Menggunakan Router untuk menghubungkan tiga  IP Network yang berbeda, tetapi masih menggunakan VLAN yang sama, yaitu VLAN 1<br />
2. Ada <a href="http://technorati.com/tag/3">3</a> bagian yg harus di lakukan <a href="http://technorati.com/tag/config">config</a>urasi, yaitu : Router, Switch dan PC<br />
<a href="http://technorati.com/tag/3">3</a>. Koneksi Router dengan Switch, jika terhubung dengan interface Fa0/0 atau Fa0/1 Cable connectionnya menggunakan Straight.<br />
4. Koneksi <a href="http://technorati.com/tag/router">router</a> dengan switch, jika terhubung dengan HWIC-4ESW maka cable connectionnya harus menggunakan Cross Cable. hal ini dikarenakan HWIC-4ESW adalah L2<br />
5. Process Pengalamatan IP pada interface HWIC-4ESW harus menggunakan VLAN sebagai konektifitasnya</p>
<p><strong>Berikut ini konfigurasi pada masing-masing device :</strong></p>
