address-family l2vpn evpn

Use address-family l2vpn evpn to create the BGP EVPN address family and enter its view, or enter the view of the existing BGP EVPN address family.

Use undo address-family l2vpn evpn to delete the BGP EVPN address family and all settings in BGP EVPN address family view.

Syntax

address-family l2vpn evpn

undo address-family l2vpn evpn

Default

The BGP EVPN address family does not exist.

Views

BGP instance view

Predefined user roles

network-admin

Usage guidelines

Configuration made in BGP EVPN address family view takes effect only on routes and peers of the BGP EVPN address family that are on the public network.

Examples

# Create the BGP EVPN address family and enter its view.

<Sysname> system-view

[Sysname] bgp 100

[Sysname-bgp-default] address-family l2vpn evpn

[Sysname-bgp-default-evpn]

arp mac-learning disable

Use arp mac-learning disable to disable an EVPN instance from learning MAC addresses from ARP information.

Use undo arp mac-learning disable to restore the default.

Syntax

arp mac-learning disable

undo arp mac-learning disable

Default

An EVPN instance learns MAC addresses from ARP information.

Views

EVPN instance view

Predefined user roles

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

display bgp l2vpn evpn

Use display bgp l2vpn evpn to display BGP EVPN routes.

Syntax

display bgp [ instance instance-name ] l2vpn evpn [ peer ipv4-address { advertised-routes | received-routes } [ statistics ] | [ route-distinguisher route-distinguisher | route-type { auto-discovery | es | imet | mac-ip } ] * [ { evpn-route route-length | evpn-prefix } [ advertise-info ] | ipv4-address | ipv6-address | mac-address ] | statistics ]

Views

System view

Predefined user roles

network-admin

Usage guidelines

Use this command only on an EVPN network.

By default, the device issues a remote MAC address entry to the hardware after the remote MAC address is advertised to the local site by BGP EVPN routes. This feature enables the device to issue a remote MAC address entry to the hardware only when the entry is required for packet forwarding. This feature saves hardware resources on the device.

With this feature enabled, the device generates a blackhole MAC address entry for an unknown MAC address if receiving 50 frames destined for that MAC address within the MAC aging time. For more information about the MAC aging time and blackhole MAC address entries, see MAC address table configuration in Layer 2—LAN Switching Configuration Guide.

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.

Examples

# Configure 22:1 as the RD of an EVPN instance.

Parameters

ext-comm-list-number: Specifies an extended community attribute list by its number in the range of 1 to 199.

Usage guidelines

This command enables an RR to reflect only received BGP EVPN routes that match the attributes in the specified extended community attribute list.

If a cluster contains multiple RRs, you can configure different reflection policies on the RRs for load sharing among the RRs.

For more information about the extended community attribute list, see Layer 3—IP Routing Configuration Guide.

Default

EVPN does not have route targets.

Views

EVPN instance view

Predefined user roles

network-admin

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.

Examples

# Configure import route targets 10:1, 100:1, and 1000:1 for an EVPN instance.
