The methods include observing a network topology transition affecting a first path from the particular node to a root node, calculating a second path from the particular node to the root node and sending a message to an upstream node requesting that the upstream node be a root port in the calculated second path. If the upstream node agrees to be the root port in the calculated second path, the method further includes creating a new FTAG tree topology view that includes the upstream node as the root port in the second path."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for constructing a loop free multicast tree in a data-center fabric","description":"Systems, methods and transitory computer-readable storage media for constructing a loop free multicast tree.
