Abstract
An example method for calculating a constrained distribution tree in a TRILL network including a plurality of VL and FGL RBridges can include learning an FGL multi-destination frame filtering capability of at least one of the FGL RBridges in the TRILL network, constructing a sub-graph including the FGL RBridges and associated links and calculating at least one sub-tree based on the sub-graph. The method can also include constructing a graph including VL RBridges, the FGL RBridges and associated links by adding links between the VL RBridges and the FGL RBridges. The FGL RBridge to which the VL RBridge is linked can have sufficient FGL multi-destination frame filtering capability. Further, the method can include calculating a constrained distribution tree based on the graph by treating the sub-tree as a logical node.
