Scenarios when to use Multicast Routing
I would like to know in which scenario an environment needs to configure Multicast Routing.
Most of the cases I have seen when there is a live event the employees can attend remotely , it usually is made available online through some kind of web links.
The same thing when there is a meeting between employees from different regions.
I have not seen any scenario that requires configuration of Multicast Routing in the network.
Any clarification ?
Thank you

I have read about What Multicast is.
I need to know scenarios where an an environment needs to implement Multicast.
I know if you are using EIGRP then there is sort of Multicast used between routers to communicate to 224.0.0.10 if I am not wrong , if OSPF is used the 224.0.0.5 and 224.0.0.6 is used.
However using EIGRP or OSPF, does not require to enable multicast at the global configuration level of the router nor at the interface level

Thank you Guys...
I will come back to this topic later

A multicast group identifies a set of recipients that are interested in a particular data stream, and is represented by an IP address from a well-defined range. Data sent to this IP address is forwarded to all members of the multicast group.
There are many different multicast protocols and modes of operation, each optimized for a particular scenario. Many of these are still at an early stage of standardization. However, they all operate in the same general way, as follows.
A Multicast Group Membership Discovery protocol is used by receiving hosts to advertise their group membership to a local multicast router, enabling them to join and leave multicast groups. The main Multicast Group Membership Discovery protocols are Internet Group Management Protocol (IGMP) for IPv4 and Multicast Listener Discovery (MLD) for IPv6.
A Multicast Routing Protocol is used to communicate between multicast routers and enables them to calculate the multicast distribution tree of receiving hosts. Protocol Independent Multicast (PIM) is the most important Multicast Routing Protocol.
