Abstract
A Layer 2 network switch fabric is partitionable into a plurality of virtual fabrics. A network switch chassis is partitionable into a plurality of logical switches, each of which may be associated with one of the virtual fabrics, including a base switch. Logical switches in multiple network switch chassis are connected by logical connections, such as logical inter-switch links that use physical connections, such as extended inter-switch links between base switches, for data transport. A topology of logical connections is established that balances competing metrics, such as robustness and scalability, while maintaining alignment with the topology of the physical connections. A topology factor allows establishing different topologies with different balances between the competing metrics.
