Abstract
Aggregation switches are connected to an edge node by a multi-chassis link aggregation group and a virtual fiber link provides a connection for exchange of information between the aggregation switches regarding MAC addressing to synchronize MAC address tables across the aggregation switches. When failure of the virtual fiber link is detected, the multi-chassis link aggregation group is reconfigured into two or more link aggregates with each link aggregate connecting the edge node to one of the aggregation switches. A spanning tree protocol is initiated over the link aggregates to prevent loops in the network. MAC address tables are flushed and relearned with the two or more link aggregates.
