Multicast VLAN Registration

In this section:

  1. MVR Overview
    Internet Group Management Protocol (IGMP), which is used for IPv4 network multicasting, uses the resources inefficiently in Layer 2 networks. For example, a multicast stream received on one VLAN in a Layer 2 network is distributed to interfaces only within that VLAN, which could be a problem when receivers are in different VLANs. This inefficiency also poses the issue of duplication of multicast streams when hosts in multiple VLANs request the same multicast stream, which wastes the bandwidth. Multicast VLAN Registration (MVR) enables more efficient distribution of Internet Protocol Television (IPTV) multicast streams across a Layer 2 network. The duplication of multicast streams from the same source is eliminated while maintaining isolation between hosts on different VLANs.
