Calling the socket option MRT_FLUSH will allow any combination of the four flag options to be cleared. MRT_FLUSH_MFC will clear all non static mfc entries and clear the unresol= ved cache MRT_FLUSH_MFC_STATIC will clear all static mfc entries MRT_FLUSH_VIFS will clear all non static interfaces MRT_FLUSH_VIFS_STATIC will clear all static interfaces.
