A communication path selection method for sending a message between a sending communication device and a receiving communication device in a communication network includes a link aggregation group bitmap, identifying all communication paths belonging to a link aggregation group, and a trial destination bitmap, identifying all communication paths identified as trial destination paths by a routing mechanism in the sending communication device. The link aggregation group communication paths are compared to the trial destination communication paths and if at least one path belongs to both groups, a path selection table is enabled to provide a path number identifying the selected communication path by which the message is to be sent.
