Patent abstract
In one embodiment, the invention relates to a method in which at least two aggregation devices, which logically operate as a single device, are interconnected by an Inter Switch Trunk (IST) link. Thereafter, forwarding records of local routing instances between the at least two aggregation devices are synchronized to enable one aggregation device to support data traffic for the other aggregation device if it has failed or a link to the aggregation device has failed.
