Configuring the Data MDT Group Range

The provider edge (PE) router implementing data MDTs for a local multicast source must be configured with a range of multicast group addresses. Group addresses that fall within the configured range are used in the join messages for the data MDTs created in this VRF instance. The group address range cannot overlap the default MDT group address configured for any VPN on the router. If you configure overlapping group addresses, the configuration commit operation fails.

To configure the data MDT group range, include the group-range statement:




group-range multicast-prefix;

You can include this statement at the following hierarchy levels:

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

Any multicast address range can be used as the multicast prefix, for example, 227.0.0.0/8.
