Enabling data-group reuse logging
For a given VPN, the number of VPN multicast streams to be switched to data-MDTs might exceed
the number of addresses in the data-group range. In this case, the VPN instance on the source-side
PE device can reuse the addresses in the address range. With data-group reuse logging enabled,
the address reuse information will be logged.
Attributed to the MD module, the group address reuse logging information has a severity
level
informational
. For more information about the logging information, see
Network Management
and Monitoring Configuration Guide.
Perform this task on PE devices.

Configuring BGP MDT
If PIM-SSM is running on the public network, you must configure BGP MDT.
Configuration prerequisites
Before you configure BGP MDT, complete the following tasks:
•
Configure MPLS L3VPN on the public network.
•
Configure basic BGP functions on the public network.
•
Configure PIM-SSM on the public network.
•
Determine the IP addresses of the MDT peers.
•
Determine the cluster IDs of the route reflectors.
