The topology and architecture of a collapsed backbone is a star or a rooted tree.
2.
Under this set-up, the network will illustrate the concept of a collapsed backbone topology that provides a centralised management information system ( MIS ) for higher performance interconnectivity.
3.
However, the drawback of the collapsed backbone is that if the box housing the backbone is down or there are reachability problem to the central location, the entire network will crash.
