A multicast address is a logical identifier for a group of hosts in a computer network that are ... address is used to send OSPF routing information to designated ...
For routing IP multicast traffic, OSPF supports the Multicast Open Shortest Path First (MOSPF) protocol. [4] Cisco does not include MOSPF in their OSPF implementations. [5] Protocol Independent Multicast (PIM) in conjunction with OSPF or other IGPs, is widely deployed. OSPF version 3 introduces modifications to the IPv4 implementation of the ...

Sent by multicast routers to determine which multicast addresses are of interest to systems attached to the network(s) they serve to refresh the group membership state for all systems on its network. Group-specific membership queries Used for determining the reception state for a particular multicast address. Group-and-source-specific queries
However, in multicast routing, the source address (which is a simple unicast address) is used to determine data stream direction. The source of the multicast traffic is considered upstream. The router determines which downstream interfaces are destinations for this multicast group (the destination address), and sends the packet out through the ...
In computer networking, multicast is a type of group communication where data transmission is addressed to a group of destination computers simultaneously. [1] Multicast can be one-to-many or many-to-many distribution. [2] [3] Multicast differs from physical layer point-to-multipoint communication.
Multicast routing is a method of transmitting to all subscribers registered in a group by one transmission unlike unicast routing (i.e. OSPF, RIP) which transmits 1: 1 necessary data. [2]
Originated for broadcasts and NBMA networks by the Designated Router. This LSA contains the list of routers connected to the network.The link-state ID of the type 2 LSA is the IP interface address of the DR. In OSPFv3 Network-LSAs have no address information and are network protocol independent. 3 Summary-LSAs (OSPFv2)
