Host and router implementations

The IGMP agreement is implemented on a accurate host and aural a router. A host requests associates to a accumulation through its bounded router while a router listens for these requests and periodically sends out cable queries. The FreeBSD,note 1 Linuxnote 2 and Windows operating systems abutment IGMP at the host side.

For the server ancillary implementation, the Linux case uses a apparition such as mrouted to act as an IGMP Linux router. There are aswell absolute acquisition suites (such as XORP or Quagga), which about-face an accustomed computer into a full-fledged multicast router.
