SummitStack nodes should be connected to each other in a ring topology. In a ring topology, one link is used to connect to a node and the other link is used to connect to another node. The result forms a physical ring connection. This topology is highly recommended for normal operation. The following figure shows a maximal ring topology of eight active nodes.
While a physical ring connection may be present, a ring active topology only exists if all nodes in the stack are active nodes.
