Use undo address-family ipv4 to delete the MVXLAN IPv4 address family and all settings in MVXLAN IPv4 address family view.
Syntax
address-family ipv4
undo address-family ipv4
Default
No MVXLAN IPv4 address family exists.
Views
MVXLAN view
Predefined user roles
network-admin
Examples
# In MVXLAN view of VPN instance vpna, create an MVXLAN IPv4 address family and enter its view.

[Sysname-mvxlan-vpna] address-family ipv4
[Sysname-mvxlan-vpna-ipv4]
data-delay
Use data-delay to set the data-delay period (delay period before the device switches over from the default MDT 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 MVXLAN IPv4 address family view of VPN instance vpna, set the data-delay period to 10 seconds.
<Sysname> system-view
[Sysname] multicast-vpn vxlan vpn-instance vpna mode mdt
[Sysname-mvxlan-vpna] address-family ipv4
[Sysname-mvxlan-vpna-ipv4] data-delay 10
data-group
Use data-group to specify a data group range and optionally configure the criteria for the device to initiate a switchover of the default MDT to a data MDT.
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 device never initiates a switchover of the default MDT to a data 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. The value range for this argument is 25 to 32.
mask: Specifies a subnet mask for the multicast group address, in dotted decimal notation.
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.
Usage guidelines
This command enables the device to initiate a switchover of the default MDT to a data MDT if the multicast data permitted by the specified ACL keeps arriving for a data-delay period.
On a VTEP, the data group range for an MVXLAN cannot include the following objects:
· Default group of any other MVXLAN.
· The multicast group address for VXLAN flood traffic configured by using the group command in VXLAN view.
· Data groups of any other MVXLAN.
If you execute the data-group command multiple times in the same MVXLAN IPv4 address family view, the most recent configuration takes effect.
Examples
# In MVXLAN IPv4 address family view of VPN instance vpna, specify 239.1.0.0 through 239.1.0.255 as the data group range.
<Sysname> system-view
[Sysname] multicast-vpn vxlan vpn-instance vpna mode mdt

NOTE: This command is supported only in Release 6635 and later. |
Syntax
drni local local-ipv4-address remote remote-ipv4-address
undo drni local
Default
The IP addresses of the DR member devices in a DR system are not specified.
Views

Predefined user roles
network-admin
Parameters
local-ipv4-address: Specifies the IPv4 address of the local DR member device.
remote-ipv4-address: Specifies the IPv4 address of the peer DR member device.
Usage guidelines
Execute this command on the VTEPs or border devices that form a DR system on an MVXLAN network.
When both the IPL and keepalive link go down, a DR member device uses its local IP address as the source address of multicast tunnels. As a best practice, use the public IP address of a loopback interface as the local IP address and make sure downstream devices have Layer 3 connectivity to the local IP address.
The remote IP address is used to identify the SBD-SMET and S-PMSI A-D routes sent by the peer DR member device. Specify an IP address configured on the peer DR member device as the remote IP address.
Examples
# Specify the IP addresses of the local and peer DR member devices in the DR system as 2.2.2.2 and 3.3.3.3, respectively.

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.
group group-address: Specifies a multicast group address in the policy. The address range is 224.0.1.0 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.
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.
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.
mask: Specifies a subnet mask for the multicast source address or the multicast group address.
Usage guidelines
On multicast receiver-side VTEPs, MVXLAN extranet RPF routing policies are used for multicast transmission when multicast sources and receivers are located in different VPNs.
The PIM mode in the source VPN instance and the receiver VPN instance must be the same. Only PIM-SM and PIM-SSM are supported.
When you use PIM-SM, use one of the following schemes as a best practice:
· Specifying only the multicast source address—Configure two RPF selection policies as follows:
¡ In one policy, configure the multicast source address as the RP address of the multicast group that requires inter-VPN transmission.
¡ In the other policy, specify the multicast source address of the source VPN instance.
If multiple multicast groups require inter-VPN transmission, configure a dedicated RP for the multicast groups and specify the multicast source address as the RP address in RPF selection policies.
· Specifying only the multicast group address—Configure one RPF selection policy that specifies the multicast group address of the source VPN instance.
When you use PIM-SSM, configure one RPF selection policy that contains both the multicast source address and multicast group address as a best practice.
If an MVXLAN extranet RPF selection policy with only the multicast group address specified is configured in the receiver VPN instance, multicast traffic transmission will be interrupted in the source VPN instance.
Multicast source addresses in different MVXLAN extranet RPF routing policies cannot be the same, but they can overlap. The same restriction applies to the multicast group addresses in different MVXLAN 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.

# Configure an IPv4 MVXLAN extranet RPF selection policy to direct multicast traffic from VPN instance vpn-source to VPN instance vpn-receiver.

Parameters
interface-type interface-number: Specify an interface by its type and number.
evpn-drni-group: Configures the specified interface to provide the virtual IP address for the DR system.
|
|
NOTE: This keyword is supported only in Release 6635 and later. |
Usage guidelines
Do not specify the evpn-drni-group keyword if the device is not a DR member device. For the VTEP to obtain correct routing information, you must specify the interface used for establishing BGP peer relationship as the MVXLAN source interface.
You must specify the evpn-drni-group keyword if you execute this command on the DR member devices in a DR system. You must assign the same IP address to the MVXLAN source interfaces on them and specify that IP address as the virtual VTEP address. You do not need to use the source interface for establishing BGP peer relationships as the MVXLAN source interface.
In a DR system, each DR member device uses the MVXLAN source interface (virtual IP address of the DR system) to set up multicast MVXLAN tunnels when the DR member devices are operating correctly. When both the IPL and keepalive link go down, each DR member device uses the local IP address specified by using the drni local command to set up multicast MVXLAN tunnels.
Examples
# In MVXLAN IPv4 address family view of VPN instance vpna, specify Loopback 0 as the MVXLAN source interface. (Loopback 0 is the source interface used for establishing BGP peer relationship.)
