SYSTEM, DEVICE, AND METHOD FOR DISTRIBUTING MULTICAST ROUTING INFORMATION IN A PROTOCOL INDEPENDENT MULTICAST NETWORK

摘要

A system, device, and method for distributing multicast routing information in a Protocol Independent Multicast (PIM) domain utilizes a PIM router in the PIM domain to collect and distribute multicast routing information. The PIM muter collects interdomain multicast routing information from border routers, and distributes the interdomain multicast routing information by periodically sending a bootstrap message containing the interdomain multicast routing information. The PIM router may also send a bootstrap message containing any changed interdomain multicast routing information upo n determining that one or more interdomain multicast routes have changed.
