is never switched to a
switch-MDT.

Configuring the RPF vector feature
After you enable the RPF vector feature, the device inserts the RPF vector (IP address of the ASBR
in the local AS) in PIM join messages for other devices to perform RPF check.
Perform the configurations on the PE (except the PE that do not have attached receivers).
To configure the RPF vector feature:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter VPN instance view.
ip vpn-instance
vpn-instance-name
N/A
3.
Enable the RPF vector
feature.
multicast rpf proxy vector
Required.
Disabled by default.
4.
Enable RPF vector
compatibility.
multicast rpf-proxy-vector
compatible
Required.
Disabled by default.
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 address 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.
Configuration guidelines
•
Attributed to the MD module, the group address reuse logging information has a severity level
of
informational
. For more information about the logging information, see
Network
Management and Monitoring Configuration Guide.
•
When switch-group reuse logging is enabled, the generated group address reuse logging
information will be sent to the information center. The output rules for the logging information
depends on the information center configuration. For more information about the information
center, see
Network Management and Monitoring Configuration Guide
.
Configuration procedure
Perform the following configuration on the PE.
