hi,

shared tree is made of two Shortest Path Trees:

1) SPT from receiver to RP
2) SPT from the RP to the sender


is this definition true ?

    I think you got it wrong..

    Shared tree = also called RPT, a tree rooted at the RP.
    SPT = Shortest path tree from the source to the RP (or to the receivers, depending on the RP's placement)

    This is my understanding. OFC i can be wrong.
