Connexion De Non-Vpc; Connexion De Vpc - Cisco Nexus 7000 Installation

connexion de Non-vpc

Le pair-commutateur étant activé, chaque commutateur de Nexus 7000 génère des BPDU avec le
positionnement de passerelle de racine à l'ID virtuel de passerelle et au pont désigné réglés à l'ID
physique de passerelle. Puisque les priorités sont identiques, toutes les connexions de non-vpc
toujours en avant sur le lien connecté au commutateur de Nexus 7000 avec l'ID inférieur de
passerelle (N7K-1 dans cet exemple) et au bloc sur les liens se sont connectées au commutateur
de Nexus 7000 à l'ID plus élevé de passerelle (N7K-2 dans cet exemple).
