Multicast Administrative Scoping
You use multicast scoping to limit multicast traffic by configuring it to an administratively defined topological region. Multicast scoping controls the propagation of multicast messages—both multicast group joins upstream toward a source and data forwarding downstream. Scoping can relieve stress on scarce resources, such as bandwidth, and improve privacy or scaling properties.
This section discusses the following topics that provide information about configuring multicast scoping:
For multicast scoping configuration examples, see Example: Configure Multicast Scoping Using the Scope Statement and Example: Configure Multicast Scoping Using the scope-policy Statement.
