Abstract:
In one example embodiment, a system and method are shown that includes calculating a first SPF tree for a first device, the first SPF tree including a root node and a first child node, the first device being the root node of the first SPF tree. Additionally, the system and method may include calculating a second SPF tree for a second device that is a neighbor of the first device, the second SPF tree including a root node and a first child node, the second device being the root node of the second SPF tree. Further, the system and method may include building a set of interested nodes including the second device, if the first child node if the first SPF tree and the first child node of the second SPF tree are distinct.
