Usage guidelines

This command enables the device to advertise BGP EVPN routes to the local site after the device adds the routes to the routing table of a VPN instance. The BGP EVPN routes here are IP prefix advertisement routes and MAC/IP advertisement routes that contain ARP or ND information.

Examples

# Enable BGP EVPN route advertisement to the local site for VPN instance vpn1.

<Sysname> system-view

[Sysname] bgp 100

[Sysname-bgp-default] ip vpn-instance vpn1

Predefined user roles

network-admin

Usage guidelines

The MAC information and ARP information advertised by a remote VTEP overlap. To avoid duplication, use this command to disable the learning of MAC addresses from ARP information. EVPN will learn remote MAC addresses only from the MAC information advertised from remote sites.

Examples

# Disable an EVPN instance from learning MAC addresses from ARP information.

<Sysname> system-view

[Sysname] vsi aaa

[Sysname-vsi-aaa] evpn encapsulation vxlan

[Sysname-vsi-aaa-evpn-vxlan] arp mac-learning disable

arp proxy-send enable

Use arp proxy-send enable to enable ARP request proxy.

Use undo arp proxy-send enable to disable ARP request proxy.

Syntax

arp proxy-send enable

undo arp proxy-send enable

Default

ARP request proxy is disabled on VSI interfaces.

Views

VSI interface view

Predefined user roles

network-admin

Usage guidelines

ARP request proxy allows a VSI interface to send an ARP request sourced from itself when the VTEP forwards an ARP request. This feature helps resolve certain communication issues.

In an EVPN VXLAN network, VM 1 and VM 2 are attached to VTEP 1 and VTEP 2, respectively, and the VMs are in the same subnet. The gateway interfaces of VM 1 and VM 2 are VSI-interface 1 on VTEP 1 and VSI-interface 2 on VTEP 2, respectively. The following conditions exist on the VTEPs:

·     The VTEPs have established BGP EVPN neighbor relationships.

·     EVPN is disabled from learning MAC addresses from ARP information.

·     MAC address advertisement is disabled, and advertised MAC addresses are withdrawn.

·     Remote-MAC address learning is disabled.

·     Local proxy ARP is enabled on the VSI interfaces.

·     The VSI interfaces use different IP addresses and MAC addresses.

In this network, when VM 1 attempts to communicate with VM 2, the following procedure occurs:

1.     VM 1 sends an ARP request.

2.     VTEP 1 learns the MAC address of VM 1 from the ARP request, replies to VM 1 on behalf of VM 2, and sends an ARP request to obtain the MAC address of VM 2.

3.     VTEP 2 forwards the ARP request, and VM 2 replies to VTEP 1.

4.     VTEP 2 forwards the ARP reply sent by VM 2 without learning the MAC address of VM 2 because EVPN is disabled from learning MAC addresses from ARP information.

5.     VTEP 1 does not learn the MAC address of VM 2 because remote-MAC address learning is disabled.

As a result, VM 1 fails to communicate with VM 2.

For VM 1 to communicate with VM 2, enable ARP request proxy on VSI-interface 2 of VTEP 2. When receiving the ARP request sent by VTEP 1, VTEP 2 forwards it and sends an ARP request sourced from VSI-interface 2 simultaneously, and VM 2 replies to both ARP requests. Then, VTEP 2 learns the MAC address of VM 2 from the ARP reply destined from VSI-interface 2 and advertises the MAC address to VTEP 1 through BGP EVPN routes. In this way, VTEP 1 obtains the MAC address of VM 2, and VM 1 and VM 2 can communicate.

Examples

# Enable ARP request proxy on VSI-interface 100.

<Sysname> system-view

[Sysname] interface vsi-interface 100

[Sysname-vsi-interface100] arp proxy-send enable

arp-advertising disable

Use arp-advertising disable to disable ARP information advertisement for an EVPN instance.

Use undo arp-advertising disable to restore the default.

Syntax

arp-advertising disable

undo arp-advertising disable

Default

ARP information advertisement is enabled for an EVPN instance.

Views

EVPN instance view

Predefined user roles

network-admin

Usage guidelines

In an EVPN network with distributed gateways, you can disable ARP information advertisement for a VXLAN to save resources if all its user terminals use the same EVPN gateway device. The EVPN instance of the VXLAN will stop advertising ARP information through MAC/IP advertisement routes and withdraw advertised ARP information. When ARP information advertisement is disabled, user terminals in other VXLANs still can communicate with that VXLAN through IP prefix advertisement routes.

Examples

# Disable ARP information advertisement for an EVPN instance.

<Sysname> system-view

[Sysname] vsi aaa

[Sysname-vsi-aaa] evpn encapsulation vxlan

[Sysname-vsi-aaa-evpn-vxlan] arp-advertising disable

Views

System view

Predefined user roles

network-admin

Parameters

delay-value: Specifies the DF election delay, in the range of 1 to 1200 seconds.

Usage guidelines

DF election delay defines the minimum interval allowed between two DF elections.

The DF election can be triggered by site-facing interface status changes, redundant VTEP membership changes, and interface ESI changes. To prevent frequent DF elections from degrading network performance, set the DF election delay.

Examples

# Set the DF election delay to 5 seconds.

<Sysname> system-view

[Sysname] evpn multihoming timer df-delay 5

evpn route arp-mobility suppression

Use evpn route arp-mobility suppression to enable ARP mobility event suppression.

Use undo evpn route arp-mobility suppression to disable ARP mobility event suppression.

Syntax

evpn route arp-mobility suppression

undo evpn route arp-mobility suppression

Default

ARP mobility event suppression is disabled.

Views

System view

Predefined user roles

network-admin

Usage guidelines

Misconfiguration of IP addresses might cause two sites attached to different distributed EVPN gateways to contain the same IP address. In this condition, the gateways constantly synchronize and update EVPN ARP entries and determine that ARP mobility events occur. As a result, an inter-site loop might occur, and the bandwidth is occupied by ARP entry synchronization traffic. To eliminate loops and suppress those ARP mobility events, enable ARP mobility event suppression on distributed EVPN gateways. This feature allows an IP address to move at most four times between sites within 180 seconds. If an IP address moves more than four times within 180 seconds, distributed EVPN gateways suppress the excess ARP mobility events and do not advertise ARP information for the IP address.

Examples

# Enable ARP mobility event suppression.

<Sysname> system-view

[Sysname] evpn route arp-mobility suppression

export route-policy

Use export route-policy to apply an export routing policy to EVPN on a VPN instance.

Use undo export route-policy to restore the default.

Syntax

Views

VPN instance EVPN view

Predefined user roles

network-admin

Parameters

route-policy: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters.

Usage guidelines

You can specify an export routing policy to filter advertised routes or modify their route attributes for EVPN.

If you execute this command multiple times, the most recent configuration takes effect.

EVPN can use an export routing policy specified in VPN instance view or in VPN instance EVPN view. Export routing policy configuration in VPN instance EVPN view takes precedence over that in VPN instance view.

Examples

# Apply export routing policy poly-1 to EVPN on VPN instance vpn1.

<Sysname> system-view

[Sysname] ip vpn-instance vpn1

ip forwarding-conversational-learning

Use ip forwarding-conversational-learning to enable conversational learning for host route FIB entries.

Use undo ip forwarding-conversational-learning to disable conversational learning for host route FIB entries.

Syntax

ip forwarding-conversational-learning [ aging aging-time ]

undo ip forwarding-conversational-learning

Default

Conversational learning is disabled for host route FIB entries.

Views

System view

Predefined user roles

network-admin

Parameters

aging aging-time: Specifies an aging timer in minutes for host route FIB entries, in the range of 60 to 1440. The default value is 60.

Usage guidelines

Use this command only on an EVPN network.

By default, the device issues a host route FIB entry to the hardware after the entry is generated. This feature enables the device to issue a host route FIB entry to the hardware only when the entry is required for packet forwarding. This feature saves hardware resources on the device.

Set an appropriate aging timer for host route FIB entries according to your network. A much longer or shorter aging timer will degrade the device performance.

·     If the aging timer is too long, the device will save many outdated host route FIB entries and fail to accommodate the most recent network changes. These entries cannot be used for correct packet forwarding and exhaust FIB resources.

·     If the aging timer is too short, the device will delete the valid host route FIB entries that can still be effective for packet forwarding. As a result, FIB entry flapping will occur, and the device performance will be affected.

Parameters

vxlan-id: Specifies a VXLAN ID in the range of 0 to 16777215.

Usage guidelines

On distributed EVPN gateways, you must configure L3 VXLAN IDs for the gateways to differentiate traffic of different VPN instances.

To forward Layer 3 traffic of a VPN instance, you must assign an L3 VXLAN ID to the VSI interface of the VPN instance. To forward Layer 3 traffic of the public network, you must assign the same L3 VXLAN ID to the public instance and the VSI interface of the public instance.

To modify the L3 VXLAN ID for the public instance, you must first delete the original L3 VXLAN ID.

Examples

# Configure the L3 VXLAN ID as 1000 for VSI-interface 100.

Parameters

group-name: Specifies a peer group by its name, a case-sensitive string of 1 to 47 characters. The peer group must exist.

ipv4-address: Specifies a peer by its IPv4 address. The peer must exist.

mask-length: Specifies a mask length in the range of 0 to 32. To specify a subnet, you must specify both the ipv4-address and mask-length arguments.

Usage guidelines

An EVPN gateway route is the route for the IP address of a VSI interface on an EVPN gateway. By default, the EVPN gateway routes advertised by an EVPN gateway contain the default-gateway extended community attribute. The EVPN gateway routes with that attribute cannot be used as ECMP routes. You can use this command to remove the default-gateway extended community attribute from EVPN gateway routes for the routes to be used for load sharing.

Predefined user roles

network-admin

Parameters

route-distinguisher: Specifies an RD, a string of 3 to 21 characters. The RD cannot be all zeros and can use one of the following formats:

·     16-bit AS number:32-bit user-defined number. For example, 101:3.

·     32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.

·     32-bit AS number:16-bit user-defined number. For example, 65536:1. The AS number must be equal to or greater than 65536.

auto: Automatically generates an RD in the N:VXLAN ID format. The initial value of N is 1. If N:VXLAN ID is already in use, the system increases the value of N by 1 until the RD is available.

router-id: Automatically generates an RD based on the router ID in the Router ID:N format. The initial value of N is 1. If Router ID:N is already in use, the system increases the value of N by 1 until the RD is available. If you do not specify this keyword with the auto keyword, the system automatically generates an RD based on the VXLAN ID in the N:VXLAN ID format.

Usage guidelines

EVPN uses MP-BGP to advertise BGP EVPN routes for automatic VTEP discovery, MAC reachability information advertisement, and host route advertisement. MP-BGP uses the RD to differentiate BGP EVPN routes of different EVPN instances.

Parameters

vpn-target&<1-8>: Specifies a space-separated list of up to eight route targets. Each route target is a string of 3 to 21 characters in one of the following formats:

·     16-bit AS number:32-bit user-defined number. For example, 101:3.

·     32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.

·     32-bit AS number:16-bit user-defined number. For example, 65536:1. The AS number must be equal to or greater than 65536.

auto: Automatically generates a route target in the format of BGP AS number:VXLAN ID.

both: Uses the specified route targets as both import and export targets. If you do not specify the both, export-extcommunity, or import-extcommunity keyword, the both keyword applies.

export-extcommunity: Uses the specified route targets as export targets.

import-extcommunity: Uses the specified route targets as import targets.

all: Specifies all route targets.

Usage guidelines

EVPN uses MP-BGP to advertise BGP EVPN routes for automatic VTEP discovery, MAC reachability information advertisement, and host route advertisement. MP-BGP uses route targets to control the advertisement and acceptance of BGP EVPN routes.

A VTEP sets the export targets for BGP EVPN routes before advertising the routes to remote VTEPs. The VTEP checks the export targets of BGP EVPN routes from remote VTEPs and imports only BGP EVPN routes of which the export targets match the local import targets.

If you execute this command multiple times, all configured route targets take effect.
