Abstract
A method and system is provided for a virtual local network to span multiple loop free network topology domains. According to one aspect of the invention, a network contains at least two loop free network topology domains and a virtual local area network spanning at least a portion of each of the two domains. According to one aspect of the invention, a network architecture comprises a plurality of nodes connected by paths, a first physical broadcast domain and a second physical broadcast domain each comprising a separate subset of the plurality of nodes, and a logical broadcast domain comprising a node from each subset.
