Multicast Data Center Deployment Recommendations

This section discusses the recommended and optional configurations for IP multicast data center deployment. The recommended guidelines are summarized below:

Place multicast sources on a separate VLAN that is attached to the aggregation layer. Sources that require direct access to back-end resources (such as the application, database, or storage layers) are placed in the front-end layer.

Use administratively scoped addresses to differentiate multicast applications by type and bandwidth.
