To implement the multicast routing, Internet Group Management Protocol (IGMP) and a multicast routing protocol (Reverse-path forwarding, PIM-SM) for registration subscriber grouping and control traffic are required for multicast transmission. [2] [3] [4] Regarding IP multicast, it is a technique for one-to-many communication over an IP network ...
Multiprotocol Extensions for BGP (MBGP or MP-BGP), sometimes referred to as Multiprotocol BGP or Multicast BGP and defined in IETF RFC 4760, [1] is an extension to Border Gateway Protocol (BGP) that allows different types of addresses (known as address families) to be distributed in parallel.
The router generates a routing table with the multicast group of which it has knowledge with corresponding distances (i.e. number of devices/routers between the router and the destination). When a multicast packet is received by a router, it is forwarded by the router's interfaces specified in the routing table.
It is termed protocol-independent because PIM does not include its own topology discovery mechanism, but instead uses routing information supplied by other routing protocols. PIM is not dependent on a specific unicast routing protocol; it can make use of any unicast routing protocol in use on the network. PIM does not build its own routing tables.
Multicast RPF, typically denoted simply as RPF, is used in conjunction with a multicast routing protocol such as Multicast Source Discovery Protocol or Protocol Independent Multicast to ensure loop-free forwarding of multicast packets. In multicast routing, the decision to forward traffic is based upon source address and not on destination ...
In IP multicast the implementation of the multicast concept occurs at the IP routing level, where routers create optimal distribution paths for datagrams sent to a multicast destination address. Multicast is often employed in Internet Protocol (IP) applications of streaming media , such as IPTV and multipoint videoconferencing .
