static multicast router daemon
SMCRoute is a daemon and command line tool to manipulate the multicast
routing table of a UNIX kernel. It can be used as an alternative to
dynamic multicast routers like pimd, mrouted, quagga-pimd, or xorp in
situations where static multicast routes should be maintained and/or no
proper IGMP signaling exists.
