Multicast VPN commands
address-family ipv4
Use address-family ipv4 to create an MVPN IPv4 address family and enter its view, or enter the view of the existing MVPN IPv4 address family.
Use undo address-family ipv4 to delete the MVPN IPv4 address family and configurations in MVPN IPv4 address family view.
Syntax
address-family ipv4
undo address-family ipv4
Default
No MVPN IPv4 address family exists.
Views
MVPN view
Predefined user roles

Usage guidelines
Configurations in MVPN IPv4 address family view of a VPN instance apply only to IPv4 multicast packets of that instance.
Examples
# In MVPN view of VPN instance mvpn, create an MVPN IPv4 address family and enter its view.
<Sysname> system-view
[Sysname] multicast-vpn vpn-instance mvpn mode mdt
[Sysname-mvpn-mvpn] address-family ipv4
[Sysname-mvpn-mvpn-ipv4]
address-family ipv4 mdt
Use address-family ipv4 mdt to create a BGP IPv4 MDT address family and enter its view, or enter the view of the existing BGP IPv4 MDT address family.
Use undo address-family ipv4 mdt to delete the BGP IPv4 MDT address family and all configurations in BGP IPv4 MDT address family view.
Syntax
address-family ipv4 mdt
undo address-family ipv4 mdt
Default
No BGP IPv4 MDT address family exists.
Views
BGP instance view
Predefined user roles
network-admin
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.
<Sysname> system-view
[Sysname] bgp 100 instance abc
[Sysname-bgp-abc] address-family ipv4 mdt
[Sysname-bgp-abc-mdt]

address-family ipv6
Use address-family ipv6 to create an MVPN IPv6 address family and enter its view, or enter the view of the existing MVPN IPv6 address family.
Use undo address-family ipv6 to delete the MVPN IPv6 address family and configurations in MVPN IPv6 address family view.
Syntax

Default
No MVPN IPv6 address family exists.
Views
MVPN view
Predefined user roles

Usage guidelines
Configurations in MVPN IPv6 address family view of a VPN instance apply only to IPv6 multicast packets of that instance.
Examples
# In MVPN view of VPN instance mvpn, create an MVPN IPv6 address family and enter its view.
<Sysname> system-view
[Sysname] multicast-vpn vpn-instance mvpn mode mdt
[Sysname-mvpn-mvpn] address-family ipv6
[Sysname-mvpn-mvpn-ipv6]
data-delay
Use data-delay to set the data-delay period (delay period before the default-MDT switches to the data-MDT).
Use undo data-delay to restore the default.
Syntax
data-delay delay
undo data-delay
Default
The data-delay period is 3 seconds.

Parameters
delay: Specifies a data-delay period in the range of 1 to 60 seconds.
Examples
# In MVPN IPv4 address family view of VPN instance mvpn, set the data-delay period to 20 seconds.

data-group
Use data-group to specify a data group range and optionally configure the criteria for the default-MDT to data-MDT switchover.
Use undo data-group to restore the default.
Syntax
data-group group-address { mask-length | mask } [ acl acl-number ]
undo data-group
Default
No data group range exists, and the default-MDT to data-MDT switchover never occurs.

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. The value range for this argument is 25 to 32.
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.
Usage guidelines
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.
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.
The data group ranges for different MVPNs on different PE devices cannot overlap with one another if the PIM mode is not PIM-SSM on the public network.
If you execute this command multiple times for an MVPN, 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.
Examples
# In MVPN IPv4 address family view of VPN instance mvpn, specify 239.1.2.0 through 239.1.2.255 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 25
default-group
Use default-group to specify a default-group.
Use undo default-group to restore the default.
Syntax
default-group group-address
undo default-group
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 and IPv6 address family views.
Examples
# In MVPN IPv4 address family view and 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

· 32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.
· 32-bit AS number:16-bit user-defined number, where the AS number must be equal to or greater than 65536. For example, 65536:1.
ip-address: Specifies a multicast source by its IP address. The ip-address argument represents the IP address of the PE device in the default-MDT. If you do not specify a multicast source, this command displays brief information about BGP MDT routes for all multicast sources.

Usage guidelines
This feature enables PE devices to carry the RPF vector information in PIM join messages for other devices to perform RPF check on the messages.
You must enable this feature on PE devices (excluding the PE devices that do not have attached receivers) when you configure MVPN inter-AS option B.
Only the configuration made in MRIB view of a VPN instance takes effect. The configuration made in MRIB view on the public network does not take effect.
Examples
# Enable the RPF vector feature for VPN instance mvpn.
<Sysname> system-view
[Sysname] multicast routing vpn-instance mvpn mode mdt
[Sysname-mrib-mvpn] rpf proxy vector

Parameters
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.
