    abstract =  {This proposal extends the PIM-SM {[}1{]} mechanism for multicast datagram forwarding. PIM-SM constructs and maintains uni-directional shared trees and uni-directional source trees. We describe how we can extend the elements of operation of sparse-mode PIM to support bi- directional shared trees.},
