Usage guidelines
Execute this command before you use the peer enable command to enable BGP peers to exchange MDT information. MDT information includes the IP address of a PE device and the default group to which the PE device belongs. On a public network running PIM-SSM, multicast VPN establishes a default MDT rooted at the PE device (multicast source) based on the MDT information.
Configurations in BGP IPv4 MDT address family view takes effect only on BGP MDT messages, BGP MDT peers, and BGP MDT peer groups.
Examples
# In BGP instance view of BGP instance default, create a BGP IPv4 MDT address family and enter its view.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp-default] address-family ipv4 mdt
[Sysname-bgp-default-mdt]
# In BGP instance view of BGP instance abc, create a BGP IPv4 MDT address family and enter its view.

Parameters
delay: Specifies a data delay period in the range of 1 to 60 seconds.
Usage guidelines
This command is available only for MDT-based MVPNs.
Examples
# In MVPN IPv4 address family view of VPN instance mvpn, set the data delay period to 20 seconds.

network-admin
Parameters
group-address: Specifies a multicast group address in the range of 224.0.1.0 to 239.255.255.255.
mask-length: Specifies a mask length for the multicast group address.
mask: Specifies a subnet mask for the multicast group address.
acl acl-number: Specifies an advanced ACL by its number in the range of 3000 to 3999. If you specify an ACL, the multicast data permitted by the ACL can trigger the switchover. If you do not specify an ACL, any multicast data can trigger the switchover. For the ACL to take effect, 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: Sets the traffic rate threshold that triggers an MDT switchover. The value range for the threshold-value argument is 0 to 16777216 kbps, and the default is 0 kbps.
Usage guidelines
This command enables the device to trigger the default MDT to data MDT switchover when the following conditions exist:
· The VPN multicast data permitted by the ACL keeps arriving for a data delay period.
· The rate of the VPN multicast data stays higher than the traffic threshold during the data delay period.
On a PE, the data group range for an MVPN cannot include the default group or data groups of any other MVPN. For an MVPN that transmits both IPv4 and IPv6 multicast packets, the data group ranges in MVPN IPv4 address family view and MVPN IPv6 address family view cannot overlap.
All VPN instances share the data group resources. As a best practice to avoid data group resource exhaustion, specify a reasonable data group range for a VPN instance.
The data group ranges for different MDs on different PE devices cannot overlap if the PIM mode is not PIM-SSM on the public network.
The data group range specified in this command cannot contain the multicast group address for flood traffic specified by using the group command in VXLAN view. For more information about the multicast group address for VXLAN flood traffic, see basic VXLAN feature configuration in VXLAN Configuration Guide.
If you execute this command multiple times in the same MVPN IPv4 address family view or IPv6 address family view, the most recent configuration takes effect.
If BIDIR-PIM runs in a VPN instance, the switchover from the default MDT to a data MDT is not supported.
This command is available only for MDT-based MVPNs.
Examples
# In MVPN IPv4 address family view of VPN instance mvpn, specify 239.1.2.0/24 as the data group range.
<Sysname> system-view
[Sysname] multicast-vpn vpn-instance mvpn mode mdt
[Sysname-mvpn-mvpn] address-family ipv4
[Sysname-mvpn-mvpn-ipv4] data-group 239.1.2.0 24
data-holddown
Use data-holddown to set the data hold-down period (hold-down period before the device switches back from data MDT to the default MDT).
Use undo data-holddown to restore the default.
Syntax
data-holddown delay
undo data-holddown
Default
The data hold-down period is 60 seconds.

Use undo default-group to restore the default.
Syntax

Default
No default group exists.

Parameters
group-address: Specifies a default group in the range of 224.0.1.0 to 239.255.255.255.
Usage guidelines
You must specify the same default group on all PE devices that belong to the same MVPN.
The default group for an MVPN must be different from the default group and the data group used by any other MVPN.
The default group address specified in this command must be different from the multicast group address for flood traffic specified by using the group command in VXLAN view. For more information about the multicast group address for VXLAN flood traffic, see basic VXLAN feature configuration in VXLAN Configuration Guide.
For an MVPN that transmits both IPv4 and IPv6 multicast packets, you must specify the same default group in MVPN IPv4 address family view and MVPN IPv6 address family view.
This command is available only for MDT-based MVPNs.
Examples
# In MVPN IPv4 family view and MVPN IPv6 address family view of VPN instance mvpn, specify 239.1.1.1 as the default group.
<Sysname> system-view
[Sysname] multicast-vpn vpn-instance mvpn mode mdt

Predefined user roles
network-admin
Usage guidelines
Before you execute this command, you must establish BGP IPv4 MVPN neighbor relationship and specify BGP MVPN peers.
The following BGP extended community attributes are used to identify the local device as the route originator:
· Source AS Extended Community—Carries the number of AS where the MVPN source resides. The format of this attribute is 32-bit AS number:0, for example, 100:0.
· VRF Route Import Extended Community—Carries the originating address and the VPN instance to which the BGP VPNv4 route belongs. The format of the attribute is 32-bit originating address:VPN instance index, for example, 192.168.122.15:1. The value of the originating address depends on the MVPN source interface configuration.
¡ If the source command is used to specify the MVPN source interface, the originating address is the IP address of the MVPN source interface.
¡ If the source command is not used, the originating address is the router ID of the BGP instance to which the device belongs.
Examples
# Add attributes Source AS Extended Community and VRF Route Import Extended Community to routes sent to the BGP IPv4 MVPN neighbors.

interface-type interface-number: Specifies an interface by its type and number.
Usage guidelines
For the PE device to obtain correct routing information, you must specify the interface used for establishing BGP peer relationship as the MVPN source interface.
For an MVPN that transmits both IPv4 and IPv6 multicast packets, you must specify the same MVPN source interface in MVPN IPv4 and IPv6 address family views.
