Configuring Multicast Scoping with the scope Statement

To configure multicast scoping with the scope statement, specify a name for the scope, the set of router interfaces on which you are configuring scoping, and the scope's address range:




scope scope-name { 

interface [ interface-names ];

prefix destination-prefix;
}

For a list of the hierarchy levels at which you can include this statement, see the statement summary section for this statement.

When you configure multicast scoping with the scope statement, all scope boundaries must include the local scope. If this scope is not configured, it is added automatically at all scoped interfaces. The local scope limits the use of the multicast group 239.255.0.0/16 to an attached LAN.

For information about supported standards for multicast scoping, see IP Multicast Standards.
