Configuring Data MDTs

To configure multicast data MDTs, include the mdt statement:




mdt {

group-range multicast-prefix;



threshold {



group group-address { 



source source-address {

rate threshold-rate;
}


}


}



tunnel-limit limit;
}

You can include the statement at the following hierarchy levels:

[edit routing-instances routing-instance-name protocols pim]

[edit logical-systems logical-system-name routing-instances routing-instance-name protocols pim]

Note: Because MDT applies to virtual private networks (VPNs) and VPN routing and forwarding (VRF) instances, you cannot configure MDT statements in the master routing instance. If you configure MDT in the master routing instance, the configuration commit fails.

For an overview of routing instances and a detailed example of routing instance configuration, see the routing instances chapter of the JUNOS Feature Guide.

By default, creation of data MDTs is disabled.

This section describes the following tasks for configuring data MDTs:

Data MDTs require a correctly configured Layer 3 VPN for multicast. For more information about configuring Layer 3 VPNs for multicast, see Configuring Multicast for Layer 3 VPNs Using Dual PIM (Draft-Rosen).
