Usage guidelines
When local proxy ARP is enabled on distributed VXLAN IP gateways, each gateway learns ARP information independently. A gateway does not forward ARP packets destined for it to other gateways. For distributed VXLAN IP gateways to have the same ARP entries, you must enable dynamic ARP entry synchronization.
A controller or the EVPN feature can also synchronize ARP entries among distributed VXLAN IP gateways. When you use a controller or EVPN, do not enable this feature.
Examples
# Enable dynamic ARP entry synchronization for distributed VXLAN IP gateways.

Usage guidelines
ARP flood suppression reduces ARP request broadcasts by enabling the VTEP to reply to ARP requests on behalf of VMs.
This feature snoops ARP packets to populate the ARP flood suppression table with local and remote MAC addresses. If an ARP request has a matching entry, the VTEP replies to the request on behalf of the VM. If no match is found, the VTEP floods the request to both local and remote sites.
Examples
# Enable ARP flood suppression for VSI vsi1.

Parameters
c-vid: Matches frames that are tagged with the specified inner 802.1Q VLAN ID.
s-vid: Matches frames that are tagged with the specified outer 802.1Q VLAN ID.
vlan-id: Specifies an 802.1Q VLAN ID in the range of 1 to 4094.
only-tagged: Matches tagged frames. If the outer 802.1Q VLAN is not the PVID, the matching result does not differ, whether or not you specify the only-tagged keyword. If the outer 802.1Q VLAN is the PVID, the matching result depends on whether or not the only-tagged keyword is specified.
· To match only PVID-tagged frames, specify the only-tagged keyword.
· To match both untagged frames and PVID-tagged frames, do not specify the only-tagged keyword.
default: Matches frames that do not match any other Ethernet service instance on the interface. On an interface, you can configure this criterion only in one Ethernet service instance. The Ethernet service instance matches any frames if it is the only instance on the interface.
tagged: Matches any frames that have an 802.1Q VLAN tag.
untagged: Matches any frames that do not have an 802.1Q VLAN tag.
Usage guidelines
The match criteria of Ethernet service instances cannot overlap on an interface.
An Ethernet service instance can contain only one match criterion. To change the match criterion, first execute the undo encapsulation command to remove the original criterion. When you remove the match criterion in an Ethernet service instance, the mapping between the service instance and the VSI is removed automatically.
Examples
# Configure Ethernet service instance 1 on Ten-GigabitEthernet 1/0/1 to match frames that have an outer 802.1Q VLAN ID of 111.

Parameters
all: Specifies broadcast, unknown unicast, and unknown multicast traffic.
broadcast: Specifies broadcast traffic.
unknown-multicast: Specifies unknown multicast traffic.
unknown-unicast: Specifies unknown unicast traffic.
Usage guidelines
By default, the device floods broadcast, unknown unicast, and unknown multicast frames received from the local site to the following interfaces in the frame's VXLAN:
· All site-facing interfaces except for the incoming interface.
· All VXLAN tunnel interfaces.
To confine a kind of flood traffic to the site-facing interfaces, use this command to disable flooding for that kind of flood traffic on the VSI bound to the VXLAN. The VSI will not flood the corresponding frames to VXLAN tunnel interfaces.
Examples
# Disable flooding of broadcast traffic for VSI vsi1.
<Sysname> system-view
[Sysname] vsi vsi1
[Sysname-vsi-vsi1] flooding disable broadcast
group

Use undo group to restore the default.
Syntax
group group-address source source-address
undo group group-address source source-address
Default
A VXLAN uses unicast mode (head-end replication) for flood traffic. No multicast group address or source IP address is specified for multicast VXLAN packets.

Parameters
group-address: Specifies a multicast address in the range of 224.0.1.0 to 239.255.255.255.
source source-address: Specifies a source IP address for multicast VXLAN packets.
Usage guidelines
To reduce traffic sent to the transport network, use multicast mode if the network has dense flood traffic or many VTEPs.
The multicast mode supports the following multicast methods:
· PIM—VTEPs and transport network devices run PIM to generate multicast forwarding entries. On a VTEP, you can use the IP address of a loopback interface as the source IP address for multicast VXLAN packets. If the VTEP has multiple transport-facing interfaces, PIM dynamically selects the outgoing interfaces for multicast VXLAN packets.
· IGMP host—VTEPs and transport network devices run PIM and IGMP to generate multicast forwarding entries.
? Transport-facing interfaces of VTEPs act as IGMP hosts.
? Transport network devices connected to a VTEP run IGMP.
? All transport network devices run PIM.
On a VTEP, you must use the IP address of the transport-facing interface as the source IP address for multicast VXLAN packets. If the VTEP has multiple transport-facing interfaces, multicast VXLAN packets are sent to the transport network through the interface that provides the source IP address for multicast VXLAN packets.
VTEPs in a multicast-mode VXLAN can use different multicast methods.
To forward multicast traffic correctly, you must use the source IP address of an up VXLAN tunnel as the source IP address for multicast VXLAN packets.
For multicast-mode VXLANs, transport network devices must maintain multicast group and forwarding information. To reduce the multicast forwarding entries maintained by transport network devices, assign a multicast group address to multiple VXLANs. The VTEP separates traffic between VXLANs by VXLAN IDs.
|
NOTE: For VXLANs that use the same multicast group address, you must configure the same source IP address for their multicast VXLAN packets. |
If you execute the group command multiple times for a VXLAN, the most recent configuration takes effect.

Usage guidelines
You must configure an interface as an IGMP host if its IP address is the source IP address of multicast VXLAN packets. The IGMP host feature enables the interface to send IGMP reports in response to IGMP queries before it can receive traffic from a multicast group.
For this command to take effect, you must use the multicast routing command to enable IP multicast routing.

Usage guidelines
This command is applicable to an SDN network.
To reduce broadcast traffic in an SDN network, the controller synchronizes the MAC addresses that each VTEP learns among all VTEPs. On a VTEP, an interface learns MAC addresses through the following methods:
· Hardware learning—The interface learns MAC addresses through the hardware. The software periodically checks whether new MAC addresses are learned by the hardware and sends the MAC addresses to the controller. This method is slow because the MAC address check is performed periodically instead of in real time.
· Software learning—The interface learns MAC addresses through the software. The software issues MAC addresses to the hardware and sends the MAC addresses to the controller. This method is faster than the hardware learning method.
Software MAC address learning consumes more resources than the hardware learning method. As a best practice to ensure device performance, do not enable software MAC address learning if MAC addresses change frequently in the network.
Examples
# Enable software MAC address learning on Ten-GigabitEthernet 1/0/1.

interface tunnel tunnel-number: Specifies the VXLAN tunnel interface for the remote MAC address. The tunnel-number argument represents the tunnel interface number. The specified tunnel interface must already exist.
vsi vsi-name: Specifies the VSI name, a case-sensitive string of 1 to 31 characters.
Usage guidelines
A remote MAC address is the MAC address of a VM in a remote site.
Remote MAC entries include the following types:
· Static—Manually added MAC entries.
· Dynamic—MAC entries learned in the data plane from incoming traffic on VXLAN tunnels.
· OpenFlow—MAC entry issued by a remote controller through OpenFlow.
· OVSDB—MAC entry issued by a remote controller through OVSDB.
For a remote address, the manual static entry has higher priority than the dynamic entry.

Parameters
destination-mac mac-address: Specifies a destination MAC address in H-H-H format for BFD control packets. The MAC address can be a remote VTEP address or a multicast address. You can omit the consecutive zeros at the beginning of each segment. For example, you can enter f-e2-1 for 000f-00e2-0001.
Usage guidelines
Enable BFD on both ends of a VXLAN tunnel for quick link connectivity detection. The VTEPs periodically send BFD single-hop control packets to each other through the VXLAN tunnel. A VTEP sets the tunnel state to Defect if it has not received control packets from the remote end for 5 seconds. In this situation, the tunnel interface state is still Up. The tunnel state will change from Defect to Up if the VTEP can receive BFD control packets again.
Examples
# Enable BFD on VXLAN tunnel interface Tunnel 9, and specify 1-1-1 as the destination MAC address for BFD control packets.

Usage guidelines
By default, the device learns ARP information of remote VMs from packets received on VXLAN tunnel interfaces. To save resources on VTEPs in an SDN transport network, you can temporarily disable remote ARP learning when the controller and VTEPs are synchronizing entries. After the entry synchronization is completed, use the undo vxlan tunnel arp-learning disable command to enable remote ARP learning.
As a best practice, disable remote ARP learning for VXLANs only when the controller and VTEPs are synchronizing entries.

Parameters
vsi-name: Specifies the VSI name, a case-sensitive string of 1 to 31 characters.
access-mode: Specifies an access mode. The default access mode is VLAN.
ethernet: Specifies the Ethernet access mode.
vlan: Specifies the VLAN access mode.
track track-entry-number&<1-3>: Specifies a space-separated list of up to three track entry numbers in the range of 1 to 1024. The AC is up only if a minimum of one associated track entry is in positive state.
Usage guidelines
To monitor the status of an AC, associate it with track entries.
To configure this command for an Ethernet service instance, you must first use the encapsulation command to add a traffic match criterion to the service instance.
For traffic that matches the Ethernet service instance, the system uses the VSI's MAC address table to make a forwarding decision.
The access mode determines how a VTEP processes the 802.1Q VLAN tags in the inner Ethernet frames assigned to the VSI.
· VLAN access mode—Ethernet frames received from or sent to the local site must contain 802.1Q VLAN tags.
? For an Ethernet frame received from the local site, the VTEP removes all its 802.1Q VLAN tags before forwarding the frame.
? For an Ethernet frame destined for the local site, the VTEP adds 802.1Q VLAN tags to the frame before forwarding the frame.
In VLAN access mode, VXLAN packets sent between VXLAN sites do not contain 802.1Q VLAN tags. VXLAN can provide Layer 2 connectivity for different 802.1Q VLANs between sites. You can use different 802.1Q VLANs to provide the same service in different sites.
· Ethernet access mode—The VTEP does not process the 802.1Q VLAN tags of Ethernet frames received from or sent to the local site.
? For an Ethernet frame received from the local site, the VTEP forwards the frame with the 802.1Q VLAN tags intact.
? For an Ethernet frame destined for the local site, the VTEP forwards the frame without adding 802.1Q VLAN tags.
In Ethernet access mode, VXLAN packets sent between VXLAN sites contain 802.1Q VLAN tags. VXLAN cannot provide Layer 2 connectivity for different 802.1Q VLANs between sites. You must use the same 802.1Q VLAN to provide the same service between sites.

Parameters
ipv4-address: Specifies an IPv4 subnet address in dotted-decimal notation.
wildcard-mask: Specifies a wildcard mask in dotted decimal notation. In contrast to a network mask, the 0 bits in a wildcard mask represent "do care" bits, and the 1 bits represent "don't care" bits. If the "do care" bits in a packet's IP address are identical to the "do care" bits in the specified subnet address, the packet is assigned to the VSI. All "don't care" bits are ignored. The 0s and 1s in a wildcard mask can be noncontiguous. For example, 0.255.0.255 is a valid wildcard mask.
ipv6-address prefix-length: Specifies an IPv6 subnet address and the address prefix length in the range of 1 to 128.
Usage guidelines
You must configure this command on VSIs that share a gateway interface. This command enables the VSI interface to identify the VSI of a packet.
You can assign a maximum of eight IPv4 and IPv6 subnets to a VSI.
You must specify a gateway interface for a VSI before you can assign subnets to the VSI. If you remove the gateway interface from the VSI, the VSI's subnet settings are automatically deleted.
For VSIs that share a gateway interface, the subnets must be unique.
