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

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.

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

Parameters
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the IPv6 multicast source belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. The PIM routing entry will select this VPN instance for the upstream RPF neighbor. If the multicast source belongs to the public network, do not specify this option.
source ipv6-source-address: Specifies a source address in the policy, which can an IPv6 multicast source address or the address of the RP designated to multicast groups. If you do not specify this option, all multicast traffic that matches the multicast group in the policy in the source VPN instance will be directed to the receiver VPN instance.
group ipv6-group-address: Specifies an IPv6 multicast group address in the policy. The address range is FFxy::/16 (excluding FFx1::/16 and FFx2::/16), where "x" and "y" represent any hexadecimal numbers in the range of 0 to F. If you do not this option, all multicast traffic that matches the source address in the policy in the source VPN instance will be directed to the receiver VPN instance.
prefix-length: Specifies an IPv6 address prefix length. For an IPv6 multicast group address, the value range for this argument is 8 to 128. For an IPv6 multicast source address, the value range for this argument is 0 to 128.
Usage guidelines
MVPN extranet RPF routing policies are used for multicast transmission when multicast sources and receivers are located in different VPNs.
The IPv6 PIM modes in the source VPN instance and the receiver VPN instance must be the same. Only IPv6 PIM-SM and IPv6 PIM-SSM are supported.
As a best practice, if IPv6 PIM-SM is used for MVPN extranet solution to implement inter-VPN multicast transmission for multiple IPv6 multicast groups, configure a dedicated RP for these groups. In addition, specify the address of the RP as the source address in RPF selection policies.
In IPv6 PIM-SM mode, you can configure only one RPF selection policy for a multicast group in a VPN instance.
To implement source-specific RPF selection in MVPN extranet, you must configure two MVPN extranet RPF routing policies as follows:
· In one policy, specify the address of the RP designated to the multicast group that requires inter-VPN multicast communication as the source address.
· In the other policy, specify the multicast source in the source VPN instance as the source address.
To implement source-and-group-specific RPF selection in MVPN extranet, you must configure two MVPN extranet RPF routing policies as follows:
· In one policy, specify the address of the RP designated to the multicast group as the source address, and specify the multicast group.
· In the other policy, specify the multicast source in the source VPN instance as the source address, and specify the multicast group.
· Make sure the multicast groups in the two policies are the same to avoid inter-VPN multicast transmission failure.
If an IPv6 MVPN extranet RPF selection policy with only the multicast group address specified is configured in the receiver VPN instance, the intra-VPN multicast traffic transmission will be interrupted.
IPv6 multicast source addresses in different MVPN extranet RPF routing policies cannot be the same, but they can be overlapped with each other. The same restriction applies to the IPv6 multicast group addresses in different MVPN extranet RPF routing policies. If multiple routing policies exist for an (S, G) entry, the device selects the policy in which the IPv6 multicast group address has the longest prefix. If multiple policies have the same prefix length, the device selects the policy in which the IPv6 multicast source address has the longest prefix.

Parameters
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the multicast source belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. The PIM routing entry will select this VPN instance for the upstream RPF neighbor. If the multicast source belongs to the public network, do not specify this option.
source source-address: Specifies a source address in the policy, which can a multicast source address or the address of the RP designated to multicast groups. If you do not specify this option, all multicast traffic that matches the multicast group in the policy in the source VPN instance will be directed to the receiver VPN instance.
group group-address: Specifies a multicast group address in the policy. The address range is 224.0.0.0 to 239.255.255.255. If you do not this option, all multicast traffic that matches the source address in the policy in the source VPN instance will be directed to the receiver VPN instance.
mask: Specifies a subnet mask for the multicast source address or the multicast group address.
mask-length: Specifies a mask length for the multicast source address or the multicast group address. For a multicast group address, the value range for this argument is 4 to 32. For a multicast source address, the value range for this argument is 0 to 32.

Multicast source addresses in different MVPN extranet RPF routing policies cannot be the same, but they can be overlapped with each other. The same restriction applies to the multicast group addresses in different MVPN extranet RPF routing policies. If multiple routing policies exist for an (S, G) entry, the device selects the policy in which the multicast group address has the longest mask. If multiple policies have the same mask length, the device selects the policy in which the multicast source address has the longest mask.
