R0106-HP MSR Router Series IP Multicast Command Reference(V7)
159
acl acl-number: Specifies an advanced ACL number in the range of 3000 to 3999. This ACL defines the
(S, G) entry or entries to which the configured MDT switchover criteria apply. If you do not specify any
ACL, the configured MDT switchover criteria apply to all (S, G) entries. To make the ACL effective, specify
the protocol type as IP, and include the source and destination keywords when you create an ACL rule.
The source and destination keywords specify a multicast source address range and a multicast group
address range, respectively.
threshold threshold-value: Specifies the traffic rate threshold that triggers MDT switchover. The value
range for the threshold-value argument is 0 to 16777216 kbps, and the default is 0 kbps.
Usage guidelines
On a PE device, the data-group address range must meet the following requirements:
• It must not include the default-group address of any MDs.
• It must not overlap with the data-group address range of any other MD.
On different devices, if the public network is not in PIM-SSM mode, the data-group address ranges for
different MDs cannot overlap.
If you execute the command multiple times in an MD, the most recent configuration takes effect.
Examples
# Configure the data-group address range in VPN instance mvpn as 239.1.2.0 to 239.1.2.255.
<Sysname> system-view
[Sysname] multicast-domain vpn-instance mvpn
[Sysname-md-mvpn] data-group 239.1.2.0 24

Use data-holddown to configure the data-holddown period (holddown period before the data-MDT
