Protocol Independent Multicast - Sparse Mode (PIM-SM) is widely deployed multicast protocol. PIM protocol is defined in [RFC7761]. As deployment for PIM protocol is growing day by day, user expects lower traffic loss and faster convergence in case of any network failure. This document provides an extension to the existing protocol which would improve the stability of the PIM protocol with respect to traffic loss and convergence time when the PIM DR is down.
