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

s-vid vlan-id : Matches frames that are tagged with the specified outer 802.1Q VLAN ID. The value range for the vlan-id argument is 1 to 4094.

Usage guidelines

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.

For more information about outer and inner 802.1Q VLAN IDs, see QinQ in Layer 2—LAN Switching Configuration Guide.

Parameters

all: Specifies broadcast, unknown unicast, and unknown multicast 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 flood traffic to the site-facing interfaces, use this command to disable flooding on the VSI bound to the VXLAN. The VSI will not flood the corresponding frames to VXLAN tunnel interfaces.

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.

Views

Predefined user roles

network-admin

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.

Examples

# Set the multicast group address to 233.1.1.1 for flood traffic in VXLAN 100. Set the source IP address to 2.1.1.1 for multicast VXLAN packets.

<Sysname> system-view

[Sysname] vsi aaa

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.

Predefined user roles

network-admin

Parameters

mac-address: Specifies a remote MAC address in H-H-H format. Do not specify a multicast MAC address or an all-zeros MAC 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.

interface tunnel tunnel-number: Specifies the VXLAN tunnel interface for the remote MAC address. The tunnel-number argument represents the tunnel interface number. The 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 can be generated by the following methods:

· Manual creation.

· Dynamic learning.

· Advertisement through by BGP EVPN.

Do not configure static remote-MAC entries for VXLAN tunnels that are automatically established by using EVPN.

· EVPN re-establishes VXLAN tunnels if the transport-facing interface goes down and then comes up. If you have configured static remote-MAC entries, the entries are deleted when the tunnels are re-established.

· EVPN re-establishes VXLAN tunnels if you perform configuration rollback. If the tunnel IDs change during tunnel re-establishment, configuration rollback fails, and static remote-MAC entries on the tunnels cannot be restored.

For more information about EVPN, see EVPN Configuration Guide.

Parameters

tunnel-number: Specifies a tunnel interface number. The value range for this argument is 0 to 32767. The tunnel must be a VXLAN tunnel.

remote-vni vxlan-id: Specifies a remote VXLAN ID in the range of 0 to 16777215. You can specify this option only for a VXLAN-DCI tunnel.

Usage guidelines

This command assigns a VXLAN tunnel to a VXLAN to provide Layer 2 connectivity for the VXLAN between two sites.

You can assign multiple VXLAN tunnels to a VXLAN, and configure a VXLAN tunnel to trunk multiple VXLANs. For a unicast-mode VXLAN, the system floods unknown unicast, multicast, and broadcast traffic to each tunnel in the VXLAN.

If two data centers use different VXLANs to convey the same service, you can use the remote-vni vxlan-id option to specify the remote VXLAN ID on each ED for the VXLANs to communicate. The EDs will replace the local VXLAN ID in VXLAN packets with the remote VXLAN ID before sending the packets to a remote ED.

Examples

# Assign VXLAN tunnels 0 and 1 to VXLAN 10000.

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 QinQ mode, which is supported only by Layer 3 subinterfaces.

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

VLAN interfaces do not support this command.

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 or Layer 3 interface, 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.

The device removes the inner 802.1Q VLAN tag of the packets received on a Layer 3 subinterface operating in QinQ access mode. VXLAN packets sent between VXLAN sites do not contain the inner 802.1Q VLAN tag, and VXLAN can provide Layer 2 connectivity for different 802.1Q VLANs between sites. For a Layer 3 subinterface to operate in QinQ access mode, you must configure unambiguous QinQ termination on it.

After you modify the access mode on a Layer 3 subinterface AC, local VMs that access the VXLAN network through the subinterface cannot communicate with remote VMs. To resolve this issue, you must clear the ARP entries on the local VMs or configure them to periodically send gratuitous ARP packets.

If you use multiple Layer 3 subinterfaces of the same main interface as ACs, you must configure the same access mode for these subinterfaces.

distributed-gateway local

Use distributed-gateway local to specify a VSI interface as a distributed gateway to provide services for the local site.

Use undo distributed-gateway local to restore the default.

Syntax

distributed-gateway local

undo distributed-gateway local

Default

A VSI interface is not a distributed gateway.

Views

VSI interface view

Predefined user roles

network-admin

Usage guidelines

If a VXLAN uses distributed gateway services, you must assign the same IP address to the VXLAN's VSI interfaces on different VTEPs. To avoid IP address conflicts, you must specify the VSI interface on each VTEP as a distributed gateway.

Examples

# Specify VSI-interface 100 as a distributed gateway.

<Sysname> system-view

[Sysname] interface vsi-interface 100

[Sysname-Vsi-interface100] distributed-gateway local

gateway subnet

Use gateway subnet to assign a subnet to a VSI.

Use undo gateway subnet to remove a subnet from a VSI.

Syntax

gateway subnet { ipv4-address wildcard-mask | ipv6-address prefix-length }

undo gateway subnet { ipv4-address wildcard-mask | ipv6-address prefix-length }

Default

No subnet is assigned to a VSI.

Views

VSI view

Predefined user roles

network-admin

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 execute this command on VSIs that share a gateway interface. This command enables the VSI interface to identify the VSI of a packet.

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.

Examples

# Assign subnet 100.0.10.0/24 to VSI vxlan.

<Sysname> system-view

[Sysname] vsi vxlan

[Sysname-vsi-vxlan] gateway subnet 100.0.10.0 0.0.0.255

gateway vsi-interface

Use gateway vsi-interface to specify a gateway interface for a VSI.

Use undo gateway vsi-interface to restore the default.

Syntax

gateway vsi-interface vsi-interface-id

undo gateway vsi-interface

Default

No gateway interface is specified for a VSI.

Views

VSI view

Predefined user roles

network-admin

Parameters

vsi-interface-id: Specifies a VSI interface by its number. The value range for this argument is 1 to 16383.

Usage guidelines

A VSI can have only one gateway interface. Multiple VSIs can share a gateway interface.

For multiple VSIs to share a VSI interface, you must assign IP addresses of different subnets to the VSI interface and specify a subnet for each VSI. If the IP addresses of a VSI interface belong to the same subnet, the VSI interface can be assigned only to one VSI.

Examples

# Specify VSI-interface 100 as the gateway interface for VSI vpna.

<Sysname> system-view

[Sysname] vsi vpna

[Sysname-vsi-vpna] gateway vsi-interface 100

ipv6 nd distributed-gateway dynamic-entry synchronize

Use ipv6 nd distributed-gateway dynamic-entry synchronize to enable dynamic ND entry synchronization for distributed VXLAN IP gateways.

Use undo ipv6 nd distributed-gateway dynamic-entry synchronize to disable dynamic ND entry synchronization for distributed VXLAN IP gateways.

Syntax

ipv6 nd distributed-gateway dynamic-entry synchronize

undo ipv6 nd distributed-gateway dynamic-entry synchronize

Default

Dynamic ND entry synchronization is disabled for distributed VXLAN IP gateways.

Views

System view

Predefined user roles

network-admin

Usage guidelines

When local ND proxy is enabled on distributed VXLAN IP gateways, each gateway learns ND information independently. A gateway does not forward ND packets destined for its local VSI interfaces to other gateways. For distributed VXLAN IP gateways to have the same ND entries, you must enable dynamic ND entry synchronization.

A controller or the EVPN feature can also synchronize ND entries among distributed VXLAN IP gateways. When you use a controller or the EVPN feature, do not enable dynamic ND entry synchronization.

Examples

# Enable dynamic ND entry synchronization for distributed VXLAN IP gateways.

<Sysname> system-view

[Sysname] ipv6 nd distributed-gateway dynamic-entry synchronize
