INTRODUCTION
qpimd aims to implement a PIM (Protocol Independent Multicast)
daemon for the FRR Routing Suite.
qpimd implements PIM-SM (Sparse Mode) of RFC 4601.
Additionally MSDP has been implemented.
In order to deliver end-to-end multicast routing control
plane, qpimd includes the router-side of IGMPv[2|3] (RFC 3376).
