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 the VSI vsi1.

<Sysname> system-view

[Sysname] vsi vsi1

Parameters

nest: Adds VLAN tags.

c-vid: Specifies an inner VLAN tag.

s-vid: Specifies an outer VLAN tag.

vlan-id: Specifies a VLAN ID in the range of 1 to 4094.

remark: Maps VLAN tags.

1-to-2: Performs one-to-two mapping to replace the VLAN tag of single tagged packets with the specified outer and inner VLAN tags.

symmetric: Applies the reverse VLAN tag processing rule to outgoing traffic. If you do not specify this keyword, VLAN tags of outgoing traffic are not processed.

Usage guidelines

To modify the VLAN tag processing rule for incoming traffic, first execute the undo l2vpn rewrite inbound command to remove the existing rule, and then execute the l2vpn rewrite inbound command.

When you use this command, follow these restrictions:

· The l2vpn rewrite inbound tag nest s-vid vlan-id c-vid vlan-id command takes effect only on untagged packets.

· The l2vpn rewrite inbound tag remark 1-to-2 command takes effect only on single tagged packets.

Default

VXLAN VSIs do not have static remote-MAC address entries.

Views

System view

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, an all-Fs 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, in the range of 0 to 10239. 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 include the following types:

· Static—Manually added MAC entries.

· Dynamic—MAC entries learned in the data plane from incoming traffic on VXLAN tunnels.

· IS-IS—MAC entry advertised through VXLAN IS-IS.

· EVPN—MAC entry advertised through BGP EVPN.

· OpenFlow—MAC entry issued by a remote controller through OpenFlow.

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

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

· ENDP or 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.

· ENDP or 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.

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

Examples

# Add the MAC address 000f-e201-0101 to the VSI vsi1. Specify Tunnel-interface 1 as the outgoing interface.

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. Alternatively, you can use VXLAN IS-IS for automatic VXLAN tunnel assignment.

You can assign a maximum of 32 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.

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 change a flood proxy tunnel for a VXLAN, perform the following tasks:

· Use the undo tunnel command to remove the flood proxy tunnel.

· Use the tunnel command to enable flood proxy on another tunnel and assign the tunnel to the VXLAN.

Examples

# Assign VXLAN tunnels 0 and 1 to VXLAN 10000.

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 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. Make sure these subnets are on the same network as one of the IP addresses on the gateway interface.

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.

Parameters

number: Specifies a network ID in the range of 1 to 16777215.

Usage guidelines

ENDP supports multiple VXLAN networks. ENDP uses network IDs to uniquely identify VXLANs. VTEPs can discover each other if they have the same network ID.

On a VTEP, NVE tunnel interfaces must use different network IDs.

Examples

# Assign a network ID of 123 to the NVE tunnel interface Tunnel 0.

Parameters

cipher: Specifies an authentication key in encrypted form.

simple: Specifies an authentication key in plaintext form. For security purposes, the authentication key specified in plaintext form will be stored in encrypted form.

string: Specifies the authentication key. Its plaintext form must be a case-sensitive string of 1 to 24 characters. Its encrypted form must be a case-sensitive string of 1 to 65 characters.

Usage guidelines

Configure ENDP authentication in an insecure network to prevent malicious registration with an ENDS.

For ENDSs and ENDCs to establish VXLAN tunnels, make sure the following requirements are met:

· ENDP authentication is enabled or disabled across the ENDSs and ENDCs.

· If ENDP authentication is enabled, all ENDCs and ENDSs in a VXLAN network use the same authentication key.

Examples

# Enable ENDP authentication on the NVE tunnel interface Tunnel 0. Specify vxlan-a as the authentication key in plaintext form.

Parameters

server-ip: Specifies the IP address of a remote ENDS.

Usage guidelines

For redundancy, you can specify a maximum of two ENDS addresses on an NVE tunnel interface. These two ENDSs work independently. The failure of one ENDS does not affect the neighbor discovery.

As a best practice, configure different ENDSs for two ENDCs on the VTEP if the ENDCs use the same IP address but different network IDs.

Examples

# Configure Tunnel 0 as an ENDC of the ENDS at 11.0.0.1.

Views

Predefined user roles

network-admin

Parameters

interval: Specifies a registration update interval in the range of 5 to 120 seconds.

Usage guidelines

ENDP uses an ENDS probe timer and a registration aging timer in addition to the ENDC register timer set by using this command.

· ENDS probe timer—Sets the interval for an ENDC to detect an ENDS. This timer is maintained on ENDCs and is fixed at 5 seconds.

· ENDC register timer—Sets the interval for an ENDC to update its registration with an ENDS. This timer defaults to 15 seconds and can be changed by using the vxlan neighbor-discovery client register-interval command on ENDCs.

· Registration aging timer—This timer is five times the ENDC register timer. This timer is maintained on ENDSs. When the registration aging timer for an ENDC expires, the ENDS removes the ENDC from its ENDC database.

When an ENDC sends a register request to join a VXLAN network, a 5-second ENDS probe timer starts. The ENDC sends a register request to the ENDS every 5 seconds until it receives a response from the ENDS.

When the ENDC receives a response from the ENDS, the ENDS probe timer stops and an ENDC register timer starts. The ENDC regularly sends register updates at the interval set by the register timer.

If the ENDC does not receive a response after sending five consecutive register packets, the ENDC clears its neighbor database and starts the ENDS probe timer.

The ENDC adds the register timer setting to each register packet. The ENDS records this timer setting when it adds the ENDC to the ENDC database. If no register update is received from the ENDC before five times the timer is reached, ENDS removes the ENDC from the VXLAN.

Examples

# Set the ENDC registration update interval to 30 seconds on the NVE tunnel interface Tunnel 0.

<Sysname> system-view

[Sysname] interface tunnel 0 mode nve

[Sysname-Tunnel0] vxlan neighbor-discovery client register-interval 30

Predefined user roles

network-admin

Parameters

value: Specifies a multiplier in the range of 3 to 1000.

Usage guidelines

Adjacency hold time sets the amount of time that the remote VTEPs can retain the adjacency with the local VTEP before an adjacency update. VTEPs send their adjacency hold time in hello packets to update the adjacencies with their neighbors. A VTEP removes the adjacency with a neighbor if it does not receive a hello packet from the neighbor before the timer expires.

· If Graceful Restart is disabled, the adjacency hold time equals the VXLAN IS-IS hello interval multiplied by the hello multiplier.

· If Graceful Restart is enabled, the adjacency hold time equals the greater value between the following settings:

¡ The restart interval.

¡ The VXLAN IS-IS hello interval multiplied by the hello multiplier.

The maximum adjacency hold time is 65535 seconds. If this value is exceeded, the actual adjacency hold time is set to 65535 seconds.

Examples

# Set the hello multiplier to 6 for calculating the VXLAN IS-IS adjacency hold time.
