    abstract =  {This document defines two PIM Join/Prune attributes that support the construction of multicast distribution trees where the root and receivers are located in different LISP sites. These attributes allow the receiver site to select between unicast and multicast underlay transport and to convey the receiver ETR's RLOC address to the control plane of the root ITR.},
