Abstract: The disclosure relates to recovering from a failure in a network. A flooding topology, represented by links between nodes in the network, is computed. Alternative connections for the links and the nodes on the flooding topology are also computed. A change in the flooding topology is detected, where the change indicates the failure in the network and results in a split of the flooding topology. A link state message is flooded to each of the nodes in a remaining part of the flooding topology and to the alternative connections, such that the link state message identifies the failure in the network. The failure in the network is resolved by connecting the split flooding topology using the remaining part of the flooding topology and the alternative connections as identified in the link state message.
