It is used for PIM control traffic
It is optionally configured for a high bandwidth multicast source to reduce multicast traffic replication to uninterested PE routers
Within the VPF configuration in the PE router, multiple Default MDT groups are configured so each VPF can support multiple multicast sources
There is a reduced multicast state in the MPLS core P routers
When multicast traffic exceeds a certain configured threshold, traffic from the Data MDT is switched to the Default MDT to conserve bandwidth
