Multicast-VPN - IP Multicast Support for MPLS VPNs
Source: Cisco Systems
This Multicast-VPN - IP Multicast Support for MPLS VPNs feature allows a service provider to configure and support multicast traffic in a Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) environment. This feature supports routing and forwarding of multicast packets for each individual VPN Routing and Forwarding (VRF) instance, and it also provides a mechanism to transport VPN multicast packets across the service provider backbone. The Multicast-VPN feature in Cisco IOS software provides the ability to support the multicast feature over a Layer 3 VPN. As enterprises extend the reach of their multicast applications, service providers can accommodate these enterprises over their MPLS core network. IP multicast is used to stream video, voice, and data to a MPLS VPN network core.
