Method for obtaining the best connectivity achievable within virtual local area networks

摘要

A method is described herein for configuring a computer network managed by the IEEE Std 802.1s(TM)-2002 MSTP standard or any other equivalent standard such as IEEE Std 802.1Q(TM)-2003 in a fully- or semi-automatic manner such that: (1) if at all possible and in the case of a failure in the MSTP-based computer network affecting a Multiple Spanning Tree Instance (MSTI), MSTP reestablishes connectivity in that MSTI by preferably activating links whose activation ensures that the connectivity within a Virtual Local Area Network (VLAN) mapped onto and associated with that MSTI is not lost; and (2) a VLAN is mapped onto a MSTI whose active topology covers the topology of this VLAN, this being ensured by setting up that MSTI depending on the desired VLAN topology.
