<h2>Contraintes imposées par le reste du cluster<a class="headerlink" href="#contraintes-imposees-par-le-reste-du-cluster" title="Lien vers cette rubrique">#</a></h2>
<p>Indépendamment des choix d’équipement, deux contraintes viennent de ce que fait l’agent.</p>
<div class="admonition warning">
<p class="admonition-title">Avertissement</p>
<p><strong>MTU</strong> — l’agent crée bridges, veth et interfaces VXLAN avec un MTU figé à 1500, et VXLAN
ajoute 50 octets d’encapsulation. Les liens entre hyperviseurs doivent donc accepter au moins
<strong>1550 octets</strong>. Cf. <a class="reference internal" href="architecture-cluster.html"><span class="doc">Architecture du cluster</span></a>.</p>
</div>
<div class="admonition warning">
<p class="admonition-title">Avertissement</p>
<p><strong>UDP 4789</strong> doit passer entre hyperviseurs, dans les deux sens : c’est le port des tunnels
VXLAN.</p>
</div>
<div class="admonition warning">
<p class="admonition-title">Avertissement</p>
<p><strong>L’API de l’agent n’a aucune authentification.</strong> Le filtrage réalisé ici est aujourd’hui
l’une des rares barrières entre cette API et le reste du réseau : son port ne doit être
joignable que depuis le réseau d’administration. Cf. <a class="reference internal" href="../exploitation/configuration.html"><span class="doc">Configuration</span></a>.</p>
