Chapter 6. Inside the Multicast Kernel 2.2.x Daemons

IF YOU WANT TO PROVIDE MULTICAST services or even just want to receive them, you need to have the routing infrastructure in place to direct multicast packets. There are a number of daemons available to serve this purpose under Linux. What we’ve chosen to cover here is a pair of daemons, each of which serves a specific purpose in the Linux multicast routing world. These are pimd for Protocol Independent Multicast-Sparse Mode (PIM-SM) and mrouted for Distance Vector Multicast Routing Protocol (DVMRP).
