This chapter discusses how other connectivity styles may be incorporated into the framework. It shows that traditional spanning trees may also be constructed. The chapter turns attention to the coercion of traffic off shortest paths, for traffic engineering purposes, without causing undesirable side effects within the routed system. It chapter turns the question round, and investigate what other uses SPB’s go return path congruency property may be put to. There were a couple of motivations for exploring alternative tree construction algorithms for SPB, driven off the common IS - IS database and set of metrics. The first motivation was a desire to provide more load spreading options in the network without significantly increasing the computational load. The other was to gain the scaling benefit of the ability to use multicast MAC trees as an adjunct to the (S,G) used by SPTs.
