    abstract =  {This document specifies an extension to PIM Join/ Prune messages. This document defines one PIM Join/ Prune attribute that support the construction of multicast distribution trees where the root and receivers are located in different Locator/ID Separation Protocol (LISP) sites using underlay IP Multicast. This attribute allows the receiver site to signal the underlay multicast group to the control plane of the root ITR (Ingress Tunnel Router).},
