Abstract
In a method for enabling facilitation of re-convergence, designation information for a first port of each one of a plurality of bridges in a multi-bridge ring is received and designation information for a second port of each one of a plurality of bridges in a multi-bridge ring is received. The first port of each one of a plurality of bridges is a first direction Ring Rapid Spanning Tree Protocol (RRSTP) port and the second port of each one of a plurality of bridges is a second direction RRSTP port. The first direction around the ring (e.g., a forward direction) is opposite the second direction around said ring (e.g., a backward direction). A first reserved MAC address is associated with the first direction port of each one of the bridges and a second reserved MAC address is associated with the second direction port of each one of the bridges.
