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.

Views

System view

Predefined user roles

network-admin

Parameters

mac-address: Specifies a MAC address in H-H-H format. Do not specify a multicast MAC address, all-zeros MAC address, or all-Fs 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 a VXLAN tunnel interface by its tunnel interface number. The value range for the tunnel-number argument is 0 to 10239. The tunnel interface must already exist.

vsi vsi-name: Specifies a 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 manually added MAC entries, dynamically learned MAC entries, and MAC entries advertised through a protocol, for example, BGP EVPN.

When you add a remote MAC address entry, make sure the specified VSI's VXLAN has been assigned the specified VXLAN tunnel.

The undo mac-address static vsi vsi-name command removes all static MAC address entries for a VSI.

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

· EVPN re-establishes 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 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.

Parameters

service-class-value: Specifies a service class value. The value range for this argument is 0 to 15.

Usage guidelines

Class Based Tunnel Selection (CBTS) compares the service class value of VXLAN packets with the service class values of MPLS TE tunnels. CBTS uses the following rules to select a tunnel to forward the traffic:

· If the packets match only one MPLS TE tunnel, CBTS uses this tunnel.

· If the packets match multiple MPLS TE tunnels, CBTS randomly selects one tunnel from them.

· If the packets do not match any MPLS TE tunnel, CBTS selects the MPLS TE tunnel that meets the following requirements:

? Its service class value is smaller than the service class value of the traffic.

? Its service class value is the nearest to the service class value of the traffic.

If multiple qualified tunnels exist, CBTS randomly selects one of them to forward the packets. If an MPLS TE tunnel is not configured with a service class value, this tunnel is preferentially selected to forward the packets.

The service class value is used only when MPLS TE tunnels are used to forward the VXLAN packets. This value is meaningless if any other tunnel is used to forward the VXLAN packets.

To set the service class value for an MPLS TE tunnel, use the mpls te service-class command. For more information about this command, see MPLS TE commands in MPLS Command Reference.

If you execute the service-class command multiple times for a VSI, the most recent configuration takes effect.

# Set the service class value to 2 for outgoing VXLAN packets.

Predefined user roles

network-admin

Parameters

tunnel-number: Specifies a tunnel interface number. The value range for this argument is 0 to 10239.The tunnel must be a VXLAN tunnel.

flooding-proxy: Enables flood proxy on the tunnel for the VTEP to send flood traffic to the flood proxy server. The flood proxy server replicates and forwards flood traffic to remote VTEPs. If you do not specify this keyword, flood proxy is disabled on the tunnel.

Usage guidelines

This command assigns a VXLAN tunnel to a VXLAN to provide Layer 2 connectivity for the VXLAN between two sites. In unicast mode, the system floods unknown unicast, multicast, and broadcast traffic to each tunnel in the VXLAN.

You can assign multiple VXLAN tunnels to a VXLAN, and configure a VXLAN tunnel to trunk multiple VXLANs.

On a VSI, you can enable flood proxy on multiple VXLAN tunnels. The first tunnel that is enabled with flood proxy works as the primary proxy tunnel to forward broadcast, multicast, and unknown unicast traffic. Other proxy tunnels are backups that do not forward traffic when the primary proxy tunnel is operating correctly.

To modify the flood proxy setting on a VXLAN tunnel, you must first use the undo tunnel command to remove the tunnel.

Examples

# Assign VXLAN tunnels 1 and 2 to VXLAN 10000.

<Sysname> system-view

Predefined user roles

network-admin

Usage guidelines

VXLAN fast forwarding enables the device to bypass QoS and security services when the device forwards data traffic over VXLAN tunnels based on the software. As a best practice, enable this feature to improve forwarding speed only when QoS and security services are not configured on the following interfaces:

· VSI interfaces.

· Traffic outgoing interfaces for VXLAN tunnels.

When VXLAN fast forwarding is enabled, a VXLAN tunnel cannot use ECMP routes to load share traffic. Instead, it selects one route from the ECMP routes to forward VXLAN packets.

Examples

# Enable VXLAN fast forwarding.

<Sysname> system

[Sysname] vxlan fast-forwarding enable

vxlan invalid-udp-checksum discard

Use vxlan invalid-udp-checksum discard to enable the device to drop the VXLAN packets that fail UDP checksum check.

Use undo vxlan invalid-udp-checksum discard to restore the default.

Syntax

vxlan invalid-udp-checksum discard

undo vxlan invalid-udp-checksum discard

Default

The device does not check the UDP checksum of VXLAN packets.

Views

Predefined user roles

network-admin

Usage guidelines

This command enables the device to check the UDP checksum of VXLAN packets.

The device always sets the UDP checksum of VXLAN packets to 0. For compatibility with third-party devices, a VXLAN packet can pass the check if its UDP checksum is 0 or correct. If its UDP checksum is incorrect, the VXLAN packet fails the check and is dropped.

Examples

# Enable the device to drop the VXLAN packets that fail UDP checksum check.

vxlan ip-forwarding

Use vxlan ip-forwarding to enable Layer 3 forwarding for all VXLANs.

Use undo vxlan ip-forwarding to enable Layer 2 forwarding for all VXLANs.

Syntax

vxlan ip-forwarding

undo vxlan ip-forwarding

Default

Layer 3 forwarding is enabled for all VXLANs.

Views.

System view

Predefined user roles

network-admin

Usage guidelines

If the device is a VTEP, enable Layer 2 forwarding for VXLANs. If the device is a VXLAN IP gateway, enable Layer 3 forwarding for VXLANs.

In Layer 3 forwarding mode, the VTEP uses the ARP table (IPv4 network) or ND table (IPv6 network) to forward traffic for VXLANs. In Layer 2 forwarding mode, the VTEP uses the MAC address table to forward traffic for VXLANs.

You must delete all VSIs, VSI interfaces, and VXLAN tunnel interfaces before you can change the forwarding mode.

Examples

# Enable Layer 3 forwarding for all VXLANs.

Predefined user roles

network-admin

Usage guidelines

When the local-MAC logging feature is enabled, the VXLAN module immediately sends a log message with its local MAC addresses to the information center. When a local MAC address is added or removed, a log message is also sent to the information center to notify the local-MAC change.

With the information center, you can set log message filtering and output rules, including output destinations. For more information about configuring the information center, see Network Management and Monitoring Configuration Guide.

Predefined user roles

network-admin

Parameters

vsi-name: Specifies the VSI name, a case-sensitive string of 1 to 31 characters.

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

For traffic that matches a 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.

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.

Examples

# Map GigabitEthernet 1/0/1 to VSI vpn1.

<Sysname> system-view

[Sysname] vsi vpn1

[Sysname-vsi-vpn1] quit

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 its local VSI interfaces 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 the EVPN feature, do not enable dynamic ARP entry synchronization.

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.

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.

Examples

# Disable remote ARP learning for VXLANs.
