Un pont se comporte comme un commutateur de réseau virtuel, fonctionnant de manière transparente (les autres machines nont pas besoin de connaître son existence). Tous les appareils réels (par exemple eth0) et virtuels (par exemple tap0) peuvent y être connectés.<br />
Cet article explique comment créer un pont qui contient au moins un dispositif ethernet. Cela est utile pour des choses comme le mode pont de la QEMU, la définition dun point daccès basé sur un logiciel, etc…</em></p>

<p>Il y a plusieurs façons de créer un pont.</p>
<h3 id="avec-iproute2">Avec iproute2</h3>
<p><em>Cette section décrit la gestion dun pont réseau à laide de loutil ip du paquet iproute2, qui est requis par le métapaquet de base.</em></p>
<p>Créez un nouveau pont et modifiez son état pour le mettre à niveau :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code># ip link add name bridge_name type bridge
# ip link set bridge_name up
</code></pre></div></div>
<p>Pour ajouter une interface (par exemple eth0) dans le pont, son état doit être en haut :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code># ip link set eth0 up
</code></pre></div></div>
<p>Lajout de linterface dans la passerelle se fait en réglant son maître sur bridge_name :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code># ip link set eth0 master bridge_name
</code></pre></div></div>
<p>Pour afficher les ponts existants et les interfaces associées, utilisez lutilitaire de pont (qui fait également partie d<a href="https://www.archlinux.org/packages/?name=iproute2">iproute2</a>). Voir <a href="https://jlk.fjfi.cvut.cz/arch/manpages/man/bridge.8">bridge(8)</a> pour plus de détails.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code># bridge link
</code></pre></div></div>
<p>Voici comment retirer une interface dun pont :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code># ip link set eth0 nomaster
</code></pre></div></div>
<p>Linterface sera toujours en haut, donc vous pouvez aussi la faire descendre :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code># ip link set eth0 down
</code></pre></div></div>
<p>Pour supprimer un pont, lancez la commande suivante :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code># ip link delete bridge_name type bridge
</code></pre></div></div>
<p>Cela supprimera automatiquement toutes les interfaces de la passerelle. Les interfaces esclaves seront toujours en place, mais vous pouvez aussi les faire tomber après.</p>

<p>Les paramètres réseau de GNOME peuvent créer des passerelles, mais actuellement, ils ne se connectent pas automatiquement à celles-ci ni aux interfaces esclaves/attachées. Ouvrez les paramètres réseau, ajoutez une nouvelle interface de type pont, ajoutez une nouvelle connexion pontée et sélectionnez ladresse MAC de lappareil à attacher au pont.</p>
<p><a href="https://www.archlinux.org/packages/?name=nm-connection-editor">nm-connection-editor</a> peut créer des ponts de la même manière que les paramètres réseau de GNOME.</p>

<p>Comment ajouter un pont réseau avec nmcli (NetworkManager) sous Linux</p>
<p><em>Un pont nest rien dautre quun appareil qui relie deux réseaux locaux en un seul réseau. Il fonctionne au niveau de la couche liaison de données, cest-à-dire la couche 2 du modèle OSI. Pont réseau souvent utilisé avec la virtualisation et dautres logiciels. La désactivation de NetworkManager pour un simple pont, en particulier sur un ordinateur portable / de bureau Linux, na aucun sens. Loutil nmcli peut créer une configuration de pont persistant sans modifier aucun fichier. Cette page montre comment créer une interface de pont à laide de loutil de ligne de commande Network Manager appelé nmcli</em></p>
<p>La procédure pour ajouter une interface de pont sous Linux est la suivante lorsque vous souhaitez utiliser Network Manager:</p>
<ol>
<li>Ouvrez lapplication Terminal</li>
<li>Obtenez des informations sur la connexion actuelle: <code class="language-plaintext highlighter-rouge">nmcli con show</code></li>
<li>Ajouter un nouveau pont: <code class="language-plaintext highlighter-rouge">nmcli con add type bridge ifname br0</code></li>
<li>Créez une interface esclave: <code class="language-plaintext highlighter-rouge">nmcli con add type bridge-slave ifname eno1 master br0</code></li>
<li>Activez br0: <code class="language-plaintext highlighter-rouge">nmcli con up br0</code></li>
</ol>
<p><strong>Obtenir la configuration actuelle du réseau</strong></p>
<p><img src="/images/bridge010.png" alt="" width="500" /></p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>nmcli con show
nmcli connection show --active
</code></pre></div></div>
<p><img src="/images/bridge011.png" alt="View the connections with nmcli" width="500" /></p>
<p>Jai une «connexion filaire 1» qui utilise linterface Ethernet eno1. Mon système dispose également dune interface VPN. Je vais configurer une interface de pont nommée br0 et ajouter (ou asservir) une interface à eno1.</p>
<p><strong>Comment créer un pont, nommé br0</strong></p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo nmcli con add ifname br0 type bridge con-name br0
sudo nmcli con add type bridge-slave ifname eno1 master br0
nmcli connection show
</code></pre></div></div>
<p><img src="/images/bridge012.png" alt="" width="500" /></p>
<p>Vous pouvez également désactiver STP:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo nmcli con modify br0 bridge.stp no
nmcli con show
nmcli -f bridge con show br0
</code></pre></div></div>
<p>La dernière commande affiche les paramètres du pont, y compris le STP désactivé:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>bridge.mac-address: -
bridge.stp: non
bridge.priority: 32768
bridge.forward-delay: 15
bridge.hello-time: 2
bridge.max-age: 20
bridge.ageing-time: 300
bridge.multicast-snooping: oui
</code></pre></div></div>
<p><strong>Comment activer linterface du pont</strong></p>
<p>Vous devez désactiver «Connexion filaire 1» et activer br0:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo nmcli con down "Wired connection 1"
sudo nmcli con up br0
nmcli con show
</code></pre></div></div>
<p>Utilisez la commande ip pour afficher les paramètres IP:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>ip a s
ip a s br0
</code></pre></div></div>
<p><img src="/images/bridge013.png" alt="" width="500" /></p>
