Explanation
of multicast distribution trees are source trees and shared trees: Source trees--The simplest form of a multicast distribution tree is a source tree, with the source at the root and the receivers at the branches. Because this tree uses the shortest path through the network, it is also referred to as a shortest path tree (SPT). Shared trees--A shared tree uses a single common root placed at a chosen point in the network. This shared root is called a Rendezvous Point (RP)
