For other P2MP multicast trees in the network that do not belong to a particular Diversity Group, you can still select the tree and perform a tuning in order to reduce the multicast tree’s cost (which is defined the total length (physical or admin-cost) of the tree). For instance, the following figure shows espntv P2MP tree is not part of Diversity Group and is a candidate for tuning.
