Using the P2MP Tree Design Feature
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 design in order to reduce the multicast tree’s cost, which is defined as the total length (physical or admin-cost) of the tree. For example, the following figure shows espntv P2MP tree is not part of Diversity Group and is a candidate for design.

The above figure is from IP/MPLSView and will be replaced with an equivalent NorthStar Planner figure shortly.
