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.
name acl-name: Specifies a basic or advanced ACL by its name, a case-insensitive string of 1 to 63 characters. The name must start with a letter and cannot be all.
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.
If you do not specify an ACL or the specified ACL does not contain rules, the data group configuration takes effect on all (S, G) entries.
The specified ACL matches traffic according to the following rules:
· A basic ACL uses the source keyword in an ACL rule to match multicast traffic by the multicast source address. All optional parameters are ignored, except source, fragment, and time-range.
· An advanced ACL uses the source and destination keywords in an ACL rule to match multicast traffic by the multicast source address and the multicast group address. All optional parameters are ignored, except source, destination, fragment, and time-range.
· If the specified basic or advanced ACL contains a rule that has the vpn-instance keyword specified, that rule does not take effect.
On a VTEP, the data group range for an MVXLAN cannot include the default group or data groups of any other MVXLAN.
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.
If you execute this command multiple times in the same MVXLAN IPv4 or IPv6 address family view, the most recent configuration takes effect.
For an MVXLAN that transmits both IPv4 and IPv6 multicast packets, you must specify the same default group in MVXLAN IPv4 address family view and IPv6 address family view, and the data group ranges in the two views cannot overlap.
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
[Sysname-mvxlan-vpna] address-family ipv4
[Sysname-mvxlan-vpna-ipv4] data-group 239.1.0.0 32
dci enable
Use dci enable to enable multicast DCI.
Use undo dci enable to disable multicast DCI.
Syntax
dci enable
undo dci enable
Default
Multicast DCI is disabled.

Usage guidelines
This command enables an ED to forward Layer 3 multicast traffic over VXLAN-DCI tunnels to remote EDs.
Examples
# Enable multicast DCI in MVXLAN IPv4 address family view of VPN instance vpna.
<Sysname> system-view
[Sysname] multicast-vpn vxlan vpn-instance vpna mode mdt
[Sysname-mvxlan-vpn-instance-vpna] address-family ipv4
[Sysname-mvxlan-vpn-instance-vpna-ipv4] dci enable
dci switch-delay
Use dci switch-delay to set the MVXLAN-specific traffic switchback delay on an ED that provides DCI Layer 3 multicast services.
Use undo dci switch-delay to restore the default.
Syntax
dci switch-delay delay-time
undo dci switch-delay
Default
The global traffic switchback delay set by using the multicast-vpn vxlan dci switch-delay command takes effect.

network-admin
Parameters
delay-time: Sets the traffic switchback delay in seconds, in the range of 0 to 3600. A value of 0 indicates that traffic switchback is not delayed.
Usage guidelines
If one of the redundant EDs fails at a multihomed site with DCI Layer 3 multicast configured, traffic of the failed ED is distributed to the other EDs for forwarding. After the failed ED recovers, it will advertise BGP EVPN routes to create multicast forwarding entries. If traffic is switched back before the recovered ED creates multicast forwarding entries, traffic forwarding is interrupted. To avoid traffic interruption, set the traffic switchback delay on all the redundant EDs.
You can set the traffic switchback delay in system view and MVXLAN address family view. The global traffic switchback delay takes effect on all MVXLANs, and the traffic switchback delay set in MVXLAN address family view takes effect on a per-MVXLAN basis. For an MVXLAN, the MVXLAN-specific traffic switchback delay takes precedence over the global one.
Examples
# Set the traffic switchback delay to 50 seconds in MVXLAN IPv4 address family view of VPN instance vpna.
<Sysname> system-view
[Sysname] multicast-vpn vxlan vpn-instance vpna mode mdt
[Sysname-mvxlan-vpn-instance-vpna] address-family ipv4
[Sysname-mvxlan-vpn-instance-vpna] dci switch-delay 50

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
The default group for an MVXLAN must be different from the default group and the data group used by any other MVXLAN.
For an MVXLAN that transmits both IPv4 and IPv6 multicast packets, you must specify the same default group in MVXLAN IPv4 address family view and IPv6 address family view, and the data group ranges in the two views cannot overlap.
Examples
# In MVXLAN IPv4 address family view of VPN instance vpna, specify 236.0.0.1 as the default group.
<Sysname> system-view
[Sysname] multicast-vpn vxlan vpn-instance vpna mode mdt

Parameters
l3-vni vxlan-id: Specifies the L3 VXLAN ID of the VPN instance to which the multicast source belongs. The value range for the vxlan-id argument is 0 to 16777215. If the multicast source belongs to the public network, do not specify this option.
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 prefix-length: Specifies a multicast group address in the policy. 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.
· The group-address argument represents the IPv6 multicast group address, and the value range for this argument is FFxy::/16, where "x" represents any hexadecimal numbers from 0 to F and "y" represents 0 or any hexadecimal characters from 2 to F.
· The prefix-length argument represents the prefix length in the range of 8 to 128.
source source-address prefix-length: Specifies a source address in the policy. 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.
· The source-address argument represents the IPv6 multicast source address.
· The prefix-length argument represents the prefix length in the range of 0 to 128.
Usage guidelines
MVXLAN extranet RPF routing policies are used for multicast transmission when multicast sources and receivers are located in different VPNs.
MVXLAN extranet RPF selection policies identify the multicast traffic to forward between VPN instances based on the L3 VXLAN ID or VPN instance of traffic.
You cannot specify both an L3 VXLAN ID and an MPLS L3VPN instance for a multicast source address and multicast group address pair.
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.
If an IPv6 MVXLAN 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.
Multicast source addresses in different IPv6MVXLAN 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.

multicast-vpn vxlan dci switch-delay
Use multicast-vpn vxlan dci switch-delay to set the global traffic switchback delay on an ED that provides DCI Layer 3 multicast services.
Use undo multicast-vpn vxlan dci switch-delay to restore the default.
Syntax
multicast-vpn vxlan dci switch-delay delay-time
undo multicast-vpn vxlan dci switch-delay
Default
The global traffic switchback delay is 10 seconds.
Views
System view
Predefined user roles
network-admin
Parameters
delay-time: Sets the traffic switchback delay in seconds, in the range of 0 to 3600. A value of 0 indicates that traffic switchback is not delayed.
Usage guidelines
If one of the redundant EDs fails at a multihomed site with DCI Layer 3 multicast configured, traffic of the failed ED is distributed to the other EDs for forwarding. After the failed ED recovers, it will advertise BGP EVPN routes to create multicast forwarding entries. If traffic is switched back before the recovered ED creates multicast forwarding entries, traffic forwarding is interrupted. To avoid traffic interruption, set the traffic switchback delay on all the redundant EDs.
You can set the traffic switchback delay in system view and MVXLAN address family view. The global traffic switchback delay takes effect on all MVXLANs, and the traffic switchback delay set in MVXLAN address family view takes effect on a per-MVXLAN basis. For an MVXLAN, the MVXLAN-specific traffic switchback delay takes precedence over the global one.
Examples
# Set the global traffic switchback delay to 50 seconds in system view.

undo multicast-vpn vxlan m-lag local
Default
The IP addresses of the member devices in an M-LAG system are not specified globally.
Views
System view
Predefined user roles
network-admin
Parameters
local-ipv4-address: Specifies the IPv4 address of the local member device.
remote-ipv4-address: Specifies the IPv4 address of the peer member device.
Usage guidelines
When you specify the IP addresses of the VTEPs or border devices in an M-LAG system, follow these restrictions and guidelines:
· IP address of the local member device—Specify the public IP address of a local loopback interface. Make sure the downstream devices have Layer 3 connectivity to this IP address. If both the peer link and keepalive link go down, the local member device will use this IP address to set up multicast tunnels.
· IP address of the peer member device—Specify an IP address on the peer M-LAG member device. This IP address is used to recognize the SBD-SMET and S-PMSI A-D routes sent by the peer M-LAG member device.
For an MVXLAN, the following settings are in descending order of priority:
· The m-lag local setting in MVXLAN address family view. This setting takes effect on a per-MVXLAN basis.
· The multicast-vpn vxlan m-lag local setting in system view. This setting takes effect on al MVXLANs.
· The evpn m-lag local setting in system view. This setting takes effect on al MVXLANs.
Examples
# Specify the IP addresses of the local and peer member devices in an M-LAG system as 2.2.2.2 and 3.3.3.3, respectively.

multicast-vpn vxlan edge remote
Use multicast-vpn vxlan edge remote to specify a peer ED for ED redundancy in the same data center for Layer 3 multicast in DCI multihoming scenarios.
Use undo multicast-vpn vxlan edge remote to remove the peer ED configuration for ED redundancy.
Syntax
multicast-vpn vxlan edge remote remote-ipv4-address
undo multicast-vpn vxlan edge remote [ remote-ipv4-address ]
Default
No peer ED is specified for ED redundancy in the same data center for Layer 3 multicast in DCI multihoming scenarios.
Views
System view
Predefined user roles
network-admin
Parameters
remote-ipv4-address: Specifies the IPv4 address of a peer ED.
Usage guidelines
To avoid single point of failure for Layer 3 multicast in DCI scenarios, you can deploy multiple EDs at the edge of a data center. On each ED, specify the IP addresses of the other EDs in the same data center in order to recognize the S-PMSI A-D routes from these EDs. This configuration avoids the local ED from joining the multicast tunnels of the other EDs in the same data center.
Repeat this command to specify the IP addresses of multiple EDs in the same data center.
If you do not specify the remote-ipv4-address argument when executing the undo multicast-vpn vxlan edge remote command, the command removes the IP addresses of all peer EDs from the local ED.
Examples
# Specify the peer EDs at 3.3.3.3 and 4.4.4.4 for ED redundancy in the same data center for Layer 3 multicast in DCI multihoming scenarios.

s-pmsi advertise source-active
Use s-pmsi advertise source-active to enable advertising active multicast sources through S-PMSI routes.
Use undo s-pmsi advertise source-active to restore the default.
Syntax

undo s-pmsi advertise source-active
Default
The device does not advertise active multicast sources through S-PMSI routes.
Views

Predefined user roles
network-admin
Usage guidelines
This command enables the VTEP to advertise an S-PMSI route for a (S, G) entry after it receives multicast traffic for the entry. The S-PMSI routes carry information about active multicast sources and allow other VTEPs and EDs in the MVXLAN network to be aware of multicast source location changes.
If you execute both the s-pmsi advertise source-active and data-group commands, set the data-delay period to be longer than the frequency of sending the same route update to a peer or peer group. If you fail to do so, BGP might suppress advertisement of the S-PMSI routes for the data group, and traffic will be interrupted during the switchover from the default MDT to the data MDT. To set the data-delay period, use the data-delay command. To set the frequency of sending the same route update to a peer or peer group, use the peer route-update-interval command.
Examples
# Enable the device to advertise active multicast sources through S-PMSI routes in MVXLAN IPv4 address family view of VPN instance vpna.
