What are multicast scope?

Multicast scope refers to the range or extent to which multicast traffic is allowed to propagate across a network. It is typically categorized into several levels: link-local (limited to a single network segment), site-local (restricted to a specific site or organization), and global (accessible across the entire internet). These scopes help manage multicast traffic efficiently, ensuring that it reaches the intended audience without unnecessary congestion on networks. Understanding multicast scope is essential for network design and optimizing resource use in multicast applications.
