Abstract
Techniques implementing redundancy in an extended bridge comprising a controller bridge (CB) unit and a plurality of port extender (PE) units are provided. In one embodiment, the CB unit can receive join requests from the plurality of PE units and can determine, based on the join requests, whether the plurality of PE units are physically connected to the CB unit and/or other CB units in the extended bridge according to a ring topology. If the plurality of PE units are physically connected to the CB unit or the other CB units according to a ring topology, the CB unit can select a link in the ring topology as being a standby link.
