Abstract

L'invention concerne un procédé et un appareil de configuration de réseau. Le procédé consiste à : déterminer qu'un premier pont routeur (RB) se joint au réseau de diffusion courant ; déterminer que le premier RB ne prend pas en charge le réseau local virtuel désigné (D-VLAN) du réseau de diffusion courant, et déterminer un premier VLAN pris en charge aussi bien par le premier RB que par un RB appartenant au D-VLAN ; envoyer des informations de D-VLAN de remplacement dans le D-VLAN et le premier VLAN, les informations de D-VLAN de remplacement comprenant l'identificateur du premier VLAN ; et lorsqu'il est déterminé que tous les états voisins dans le premier VLAN maintenu localement sont des états d'informations, envoyer des informations de transfert contenant l'identificateur du premier VLAN dans le D-VLAN, de manière à amener le RB appartenant au D-VLAN à effectuer un transfert vers le premier VLAN conformément aux informations de transfert. Le procédé et l'appareil selon les modes de réalisation de la présente invention peuvent éviter l'effet sur un transfert de trafic durant un transfert de D-VLAN et obtenir la plus grande connectivité de réseau, étant ainsi capable d'augmenter sensiblement la disponibilité du réseau.
