Abstract: An example method for convergence of multi-destination traffic in a network environment is provided and includes receiving a first type-length-value (TLV) message from a true broadcast root in a Transparent Interconnection of Lots of Links (TRILL) network, where the first TLV message indicates a first subset of multi-destination trees in the TRILL network, receiving a second TLV message from the true broadcast root indicating a second subset of multi-destination trees in the TRILL network, such that a union of the first subset and the second subset indicates at least one inactive multi-destination tree in the TRILL network, and deleting the inactive tree from a hash table of active trees.

Abstract: Techniques are provided for generating and updating flooding tree paths in a network. At a particular node device in a network, a first flooding tree is generated by performing a first shortest path first (SPF) operation from a first selected node device in the network to a plurality of other node devices in the network. A second flooding tree is generated by performing a second SPF operation from a second selected node device in the network to the plurality of other node devices in the network. A network topology change event is detected in either the first or second flooding tree, and a packet sequence exchange is initiated between the particular node device and another node device in the network in response to the detected network topology change. The first and second flooding trees are then updated based on information obtained during the packet sequence exchange.
