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 ...
MP-BGP maintains unicast and multicast routing information, and stores both types in different routing tables to ensure their separation. MP-BGP supports unicast and multicast, and constructs different network topologies for each. MP-BGP can maintain unicast and multicast routes based on routing policies.
Each multicast group to which the local router can route has a multicast routing table entry with a next hop for the group, rather than for a specific destination as in unicast routing. There can be multicast static routes as well as learning dynamic multicast routes from a protocol such as Protocol Independent Multicast (PIM).
The IP multicast standard was designed to scale to multicast groups with many members. It works well when doing a distribution similar to broadcasting, but it has scalability problems to a large number of groups. Multicast routing protocols keep routing tables that record multicast group addresses with members. These tables might become large ...
IPv6 multicast: [41] The low 32 bits an Ethernet address for IPv6 multicast traffic are the low 32 bits of the multicast IPv6 address used. [40]: §2.3.1 For example, IPv6 multicast traffic using the address ff02::d uses the MAC address 33-33-00-00-00-0D, and traffic to ff05::1:3 goes to the MAC address 33-33-00-01-00-03. 01-0C-CD IEC
In wireless networking, On-Demand Multicast Routing Protocol is a protocol for routing multicast and unicast traffic throughout Ad hoc wireless mesh networks. ODMRP creates routes on demand, rather than proactively creating routes as OLSR does. This suffers from a route acquisition delay, although it helps reduce network traffic in general.
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. PIM uses the unicast routing table for reverse-path forwarding. [1]: 56–57 There are four variants of PIM:
The routing algorithm selects the single receiver from the group based on which is the nearest according to some distance or cost measure. Unicast is the dominant form of message delivery on the Internet. This article focuses on unicast routing algorithms.
