the right definition of multicast shared tree

oudmaster

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.
