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· MAC address advertisement is disabled, and advertised MAC addresses are withdrawn.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] interface vsi-interface 100

Usage guidelines

In an EVPN VXLAN network with distributed gateways, you can disable ARP information advertisement for a VXLAN network to save resources if all its user terminals use the same EVPN gateway device. The EVPN instance of the VXLAN network 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 of EVPN VXLAN.

Predefined user roles

network-admin

Parameters

esi-id: Specifies an ES by its ESI in XXXX.XXXX.XXXX.XXXX.XXXX format. Each X represents a hexadecimal digit. The ESI must begin with 00 and cannot be all zeros.

Usage guidelines

An ESI uniquely identifies an ES. The links on interfaces, UPWs, or VSIs with the same ESI belong to the same ES. Traffic of the ES can be distributed among the links for load sharing.

You can assign ESIs to a main interface and its subinterfaces.

· If you assign an ESI to a subinterface, the subinterface-specific ESI and ES configuration take precedence over those configured on the main interface. The ES configuration includes the following:

¡ evpn redundancy-mode.

¡ evpn df-election algorithm.

¡ evpn df-election preference.

¡ evpn df-election preference non-revertive.

¡ evpn timer es-delay.

· If you do not assign an ESI to a subinterface, it inherits the ESI and redundancy mode (if configured) of the main interface. In this scenario, the redundancy mode configured on the subinterface does not take effect.

You can assign an ESI to a VSI LDP PW or VSI static PW only if you do not specify the no-split-horizon or dci keyword when executing the peer command for the PW.

To modify the ESI of an interface, UPW, or VSI, first use the undo esi command to delete the original ESI.

Examples

# Assign ESI 0000.0001.0002.0003.0004 to HundredGigE 1/0/1.

undo evpn m-lag group

Default

EVPN M-LAG is disabled.

Views

System view

Predefined user roles

network-admin

Parameters

virtual-vtep-ipv4: Specifies the virtual IPv4 VTEP address.

virtual-vtep-ipv6: Specifies the virtual IPv6 VTEP address.

virtual-vtep-ip: Specifies the virtual VTEP address.

Usage guidelines

EVPN M-LAG virtualizes two VTEPs, EDs or EVPN gateways into one M-LAG system to avoid single points of failure. The VTEPs, EDs or EVPN gateways use a virtual VTEP address to establish VXLAN or VXLAN-DCI tunnels to remote devices.

For the device to re-establish tunnels, you must execute the address-family l2vpn evpn command in BGP instance view after you enable or disable EVPN M-LAG.

To change the virtual VTEP address, first execute the undo evpn m-lag group command to remove the original virtual VTEP address.

EVPN M-LAG is mutually exclusive with EVPN-DCI dual-homing. Do not use the evpn edge group and evpn m-lag group commands together.

The evpn m-lag group and evpn m-lag local commands must specify three IPv4 or IPv6 addresses. Mixed use of IPv4 and IPv6 addresses is not allowed.

Examples

# Enable EVPN M-LAG and specify the virtual VTEP address as 1.1.1.1.

<Sysname> system-view

[Sysname] evpn m-lag group 1.1.1.1

evpn m-lag local

Use evpn m-lag local to specify the IP addresses of the VTEPs in an M-LAG system.

Use undo evpn m-lag local to restore the default.

Syntax

evpn m-lag local { local-ipv4-address remote remote-ipv4-address | local-ipv6-address remote remote-ipv6-address }

undo evpn m-lag local

Default

The IP addresses of the VTEPs in an M-LAG system are not specified.

Views

System view

Predefined user roles

network-admin

Parameters

local-ipv4-address: Specifies the IPv4 address of the local VTEP.

local-ipv6-address: Specifies the IPv6 address of the local VTEP.

remote remote-ip: Specifies the IP address of the peer VTEP.

remote-ipv4-address: Specifies the IPv4 address of the peer VTEP.

remote-ipv6-address: Specifies the IPv6 address of the peer VTEP.

Usage guidelines

An AC that is attached to only one of the VTEPs in an M-LAG system is called a single-armed AC. After you configure this command, each VTEP in an M-LAG system changes the next hop of the routes for single-armed ACs to its local VTEP IP address when advertising the routes. This ensures that the traffic of a single-armed AC is forwarded to its attached VTEP. When a VTEP receives BGP EVPN routes from the peer VTEP IP address specified by using this command, it does not set up a VXLAN tunnel to the peer VTEP.

You must execute this command if single-armed ACs are attached to an M-LAG system with a direct peer link.

When you execute this command, make sure the IP address of the local VTEP belongs to a local interface. Make sure the local VTEP IP address and peer VTEP IP address are reversed on the VTEPs in an M-LAG system.

Do not use this command on EDs.

The evpn m-lag group and evpn m-lag local commands must specify three IPv4 or IPv6 addresses. Mixed use of IPv4 and IPv6 addresses is not allowed.

Examples

# Specify the IP addresses of the local and peer VTEPs in the M-LAG system as 2.2.2.2 and 3.3.3.3, respectively.

Usage guidelines

Preference-based DF election selects the device with the highest preference as the DF. The BDF takes over the DF role if one of the following events occurs:

· The DF fails.

· The site-facing link on the DF fails.

· The DF election preference of the BDF is set to be higher than that of the DF.

When the original DF or its site-facing link recovers, or its preference is set to be higher than that of the new DF, the original DF will take over the DF role. To avoid undesired traffic loss, you can disable reversion to the original DF by enabling non-revertive mode for preference-based DF election.

This command takes effect after the evpn df-election algorithm preference command is executed in interface view or system view.

Examples

# Enable non-revertive mode for preference-based DF election.

When receiving IP prefix advertisement routes with MPLS encapsulation, the device adds the routes that belong to the VPN instance to the routing table.

For EVPN to add MPLS encapsulation to IP prefix advertisement routes, you must execute the peer advertise encap-type mpls command in BGP EVPN address family view.

Examples

# Enable EVPN to advertise the IPv4 routes of VPN instance vpna.

Predefined user roles

network-admin

Usage guidelines

Use this command on the redundant PEs at a dualhomed site.

This command enables the device to do the following:

· Withdraw the Ethernet auto-discovery routes and MAC/IP advertisement routes that have been advertised.

· Set the Ethernet tag to 0 for the Ethernet auto-discovery routes and MAC/IP advertisement routes and re-advertise them.

After you configure ESIs for ACs on the redundant edge devices at a dualhomed site, the edge devices advertise Ethernet auto-discovery routes and MAC/IP advertisement routes that carry Ethernet tags. If the remote peers are unable to identify Ethernet tags, you must execute this command on the redundant edge devices to enable communication with the peers.

When you use this command, follow these restrictions and guidelines:

· After you assign an ESI to a Layer 2 Ethernet or aggregate interface, you must map the Ethernet service instances created on the interface to different VSIs. If two interfaces use the same ESI, you must map the Ethernet service instances created on them to different VSIs.

· After you assign an ESI to a Layer 3 main interface, its subinterfaces inherit the ESI if they do not have one. In addition, you must map two subinterfaces to different VSIs if the subinterfaces have the same ESI.

Parameters

nexthop highest-ip: Configures the path with the highest next-hop IP address as the primary path in multi-homing routes.

nexthop lowest-ip: Configures the path with the lowest next-hop IP address as the primary path in multi-homing routes.

as-path: Selects the next hop with the shortest AS path as the primary path and uses the other next hop as the backup path in multi-homing routes. If the AS paths are the same, the route with a lower next-hop IP address becomes the primary path, and the one with a higher next-hop IP address acts as the backup path.

Usage guidelines

With this command executed in an EVPN VXLAN multi-homing multi-active network, the device selects the primary and backup paths based on either the next-hop IP addresses or the number of AS path hops in the received multi-homing routes. The device selects one tunnel corresponding to the next hop as the primary path and the other tunnel as the backup path.

Layer 2 forwarding uses the primary and backup path tunnels for traffic forwarding. By default, traffic travels through the primary path tunnel, and switches to the backup path tunnel if the primary one fails.

Views

network-admin

Usage guidelines

At a multihomed EVPN VXLAN network site, VM 1 is dualhomed to VTEP 1 and VTEP 2, and VTEP 1 is the DF. When the AC on VTEP 1 fails, VTEP 1 deletes the related MAC address entries and advertises the local unreachable event to VTEP 2 and remote VTEPs. Then, the remote VTEPs will switch traffic to the tunnels to VTEP 2. In this situation, VTEP 1 drops the packets that the remote VTEPs send before they are notified of the local unreachable event as the AC's MAC address entries have been deleted. To resolve this issue, enable local FRR on VTEP 1. If an AC fails, VTEP 1 changes the outgoing interface of the AC's MAC address entries to the outgoing interface of the tunnel between VTEP 1 and VTEP 2. When receiving packets from remote VTEPs after its AC fails, VTEP 1 forwards the packets to VTEP 2 over the VXLAN tunnel to prevent traffic loss.

Execute this command on the redundant VTEPs.

Predefined user roles

network-admin

Parameters

detect-cycle detect-time: Sets the ARP mobility detection cycle in seconds, in the range of 60 to 900. The default value is 180 seconds.

detect-threshold move-times: Sets the ARP mobility suppression threshold, in the range of 3 to 10. The default is 5. This threshold is the number of ARP moves from the local site to remote sites.

suppression-time: Sets the ARP mobility suppression time. A suppressed ARP entry cannot move until the ARP mobility suppression time expires. If you do not set this parameter, the default setting permanent applies.

suppression-time: Specifies the ARP mobility suppression time in seconds, in the range of 120 to 3600 seconds.

permanent: Suppresses ARP moves permanently.

Usage guidelines

The ARP mobility event suppression feature allows an IP address to move at most the specified number of times (ARP mobility suppression threshold) out of a site within an ARP mobility detection cycle. If the suppression threshold has been reached for an IP address within a detection cycle, the VTEP at the site suppresses the subsequent move after the IP address moves back to the site. In addition, the VTEP learns ARP information for the IP address but does not advertise the ARP information.

After you execute the undo evpn route arp-mobility suppression command or when the ARP mobility suppression time expires, a VTEP acts as follows:

· Advertises ARP information immediately for the suppressed ARP entries that have not aged out.

· Relearns ARP information for the suppressed ARP entries that have aged out and advertises the ARP information.

ARP mobility event suppression takes effect only on an EVPN VXLAN network configured with distributed VXLAN IP gateways.

Use undo evpn route gateway-mac unmovable to restore the default.

Syntax

evpn route gateway-mac unmovable

undo evpn route gateway-mac unmovable

Default

The static flag is not set for the MAC addresses of centralized gateway interfaces.

Views

System view

Predefined user roles

network-admin

Usage guidelines

In a network with a centralized EVPN gateway deployed, a VTEP considers a MAC address move occurs if an endpoint uses a MAC address identical to that of a centralized gateway interface. As a result, the VTEP overwrites the MAC address entry created for the centralized gateway interface with that created for the endpoint, and errors will occur in traffic forwarding.

To resolve this issue, set the static flag for the MAC addresses of centralized gateway interfaces on the centralized EVPN gateway. When advertising those MAC addresses through MAC/IP advertisement routes, the centralized EVPN gateway will set the static flag bit to 1 in the MAC mobility extended community. If an endpoint accesses the network with a MAC address identical to that of a centralized gateway interface, the endpoint's MAC address entry will not overwrite the entry for the centralized gateway interface.

Examples

# Set the static flag for the MAC addresses of centralized gateway interfaces.

Parameters

detect-cycle detect-time: Sets the MAC mobility detection cycle in seconds, in the range of 60 to 900. The default value is 180 seconds.

detect-threshold move-times: Sets the MAC mobility suppression threshold, in the range of 3 to 10. The default is 5. This threshold is the number of MAC moves from the local site to remote sites.

suppression-time: Sets the MAC mobility suppression time. A suppressed MAC entry cannot move until the MAC mobility suppression time expires. If you do not set this parameter, the default setting permanent applies.

suppression-time: Specifies the MAC mobility suppression time in seconds, in the range of 120 to 3600 seconds.

permanent: Suppresses MAC moves permanently.

Usage guidelines

On an EVPN VXLAN network, misconfiguration of MAC addresses might cause two sites to contain the same MAC address. In this condition, VTEPs at the two sites constantly synchronize and update EVPN MAC entries and determine that MAC mobility events occur. As a result, an inter-site loop might occur, and the bandwidth is occupied by MAC entry synchronization traffic. To eliminate loops and suppress those MAC mobility events, enable MAC mobility event suppression on the VTEPs.

The MAC mobility event suppression feature allows a MAC address to move at most the specified number of times (MAC mobility suppression threshold) out of a site within an MAC mobility detection cycle. If the suppression threshold has been reached for a MAC address within a detection cycle, the VTEP at the site suppresses the subsequent move after the MAC address moves back to the site. In addition, the VTEP learns the MAC address but does not advertise it.

After you execute the undo evpn route mac-mobility suppression command or when the MAC mobility suppression time expires, a VTEP acts as follows:

· Advertises MAC address entries immediately for the suppressed MAC address entries that have not aged out.

· Relearns the MAC addresses for the suppressed MAC address entries that have aged out and advertises the MAC address entries.

Parameters

detect-cycle detect-time: Specifies the ND mobility detection cycle in seconds. The value range for the detect-time argument is 60 to 900, and the default is 180.

detect-threshold move-times: Specifies the ND mobility suppression threshold, which is the number of ND moves from the local site to a remote site. The value range for the move-times argument is 3 to 10, and the default is 5.

suppression-time: Specifies the length of time that an ND entry is suppressed. After the suppression time expires, the ND entry can move again. The default suppression time is permanent.

suppression-time: Specifies the suppression time in seconds. The value range for this argument is 120 to 3600.

permanent: Suppresses ND moves permanently.

Usage guidelines

On an EVPN VXLAN network, misconfiguration of IP addresses might cause two sites to contain the same IP address. In this condition, VTEPs at the two sites constantly synchronize and update EVPN ND entries and determine that ND mobility events occur. As a result, an inter-site loop might occur, and the bandwidth is occupied by ND entry synchronization traffic. To eliminate loops and suppress those ND mobility events, enable ND mobility event suppression on the VTEPs. This feature allows an IP address to move a specified number of times (the ND mobility suppression threshold) from a site within an ND mobility detection cycle. If an IP address moves more than the ND mobility suppression threshold, the VTEP at the site will suppress the last ND move to the local site and will not advertise ND information for the IP address.

After you execute the undo evpn route nd-mobility suppression command or the suppression time expires, a VTEP acts as follows:

· Advertises ND information immediately for the suppressed ND entries that have not aged out.

· Relearns ND information for the suppressed ND entries that have aged out and advertises the ND information.

ND mobility event suppression takes effect only on the following networks:

· EVPN VXLAN network enabled with ND flood suppression.

Parameters

ipv4-address: Specifies the source IPv4 address of the BGP EVPN routes.

ipv6-address: Specifies the source IPv6 address of the BGP EVPN routes.

Usage guidelines

Operating mechanism

The function of this command varies by network type as follows:

· In an EVPN VXLAN network, this command sets the source address of BGP EVPN routes advertised by the device.

· In an EVPN VXLAN network, the device uses the address configured by using this command as the source address of the EVPN VXLAN tunnel. When other devices receive BGP EVPN routes advertised by this device, they will use this address as the destination address of their EVPN VXLAN tunnels.

Restrictions and guidelines

The IP address specified by this command must be an existing loopback address on the device.

You cannot configure both a source IPv4 address and a source IPv6 address.

Parameters

arp-learning: Disables ARP learning.

nd-learning: Disables ND learning.

Usage guidelines

On an EVPN VXLAN network deployed with a centralized EVPN gateway, VM 1 and VM 2 belong to the same VXLAN in subnet 10.1.1.0/24. The gateway interface is VSI-interface 1 and the gateway is connected to external Layer 3 network 10.1.2.0/24. The VTEP to which VM 2 is attached is configured with ARP or ND flood suppression. The IP address of VM 2 is mistakenly configured as an IP address in subnet 10.1.2.0/24 (for example, 10.1.2.2). In this situation, the VTEP connected to VM 2 advertises MAC/IP advertisement routes that contain ARP or ND information to the gateway. The IP address and MAC address in the routes are the IP address and MAC address of VM 2, respectively. The gateway learns the ARP or ND information and issues the information to the forwarding table. When VM 1 visits 10.1.2.2 in the external network, the gateway will forward the traffic to VM 2. As a result, VM 1 cannot visit 10.1.2.2.

To resolve the above issue, perform this task on the VSI interface to disable the VSI interface from learning ARP or ND information across subnets from MAC/IP advertisement routes.

Parameters

delay-time: Specifies a delay value in the range of 3 to 1200 seconds.

Usage guidelines

Use this command in combination with the evpn track peer command.

The evpn track peer command excludes unavailable edge devices from DF election at a multihomed site. After an edge device recovers from failure and brings up its CE-facing interface, it starts the advertisement delay timer for Ethernet segment routes and checks the status of the BGP peer specified in this command. If the BGP peer comes up before the timer expires, the edge device advertises Ethernet segment routes to the peer. If the BGP peer is still down when the timer expires, the edge device does not advertise Ethernet segment routes to the peer. The edge devices then perform DF election based on the Ethernet segment routes they have received.

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.

Syntax

l2vpn m-lag peer-link ac-match-rule vxlan-mapping

Default

On an M-LAG system with a direct peer link, dynamic ACs on the peer link use frame match criteria that are identical to those of site-facing ACs.

Views

System view

Predefined user roles

network-admin

Usage guidelines

By default, if an M-LAG system uses a direct peer link, each M-LAG member device creates a dynamic AC on the peer link when an AC is configured on a site-facing interface. The dynamic AC and the site-facing AC have the same frame match criteria and VSI mapping. If two site-facing ACs on different interfaces have the same frame match criteria but different VSI mappings, the dynamic ACs created for the site-facing ACs will conflict with each other. To prevent this issue, enable the M-LAG member devices to create frame match criteria based on VXLAN IDs for the dynamic ACs on the peer link.

With this command configured, an M-LAG member device creates dynamic ACs on the peer link and maps them to the VSIs of VXLANs after the VXLANs are created. The matching VLAN IDs in frame match criteria are calculated for the dynamic ACs according to the following rules:

· Outer VLAN ID = VXLAN ID / 4094 + 1.

· Inner VLAN ID = VXLAN ID % 4094 + 1.

· If the calculated outer VLAN ID of a dynamic AC is the PVID of the peer-link interface, the device uses the calculated inner VLAN ID as the outer VLAN ID. The device does not add a matching inner VLAN ID to the frame match criterion of the dynamic AC.

After you execute this command, do not create VXLANs with IDs larger than 16000000.

This command deletes existing dynamic ACs from peer-link interfaces and takes effect on all VXLANs.

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.

The L3 VXLAN ID specified by using this command cannot be the same as any VXLAN ID specified by using the mapping vni command.

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.

ipv6-address: Specifies a peer by its IPv6 address. The peer must exist.

prefix-length: Specifies a prefix length in the range of 0 to 128. To specify a subnet, you must specify both the ipv6-address and prefix-length arguments.

imet: Specifies IMET routes.

ip-prefix: Specifies IP prefix advertisement routes.

mac-ip: Specifies MAC/IP advertisement routes.

replace-rt: Replaces the L3 VXLAN ID, RD, and route targets of the IP prefix advertisement routes that match the route targets of a local VPN instance with those of the matching local VPN instance. If you do not specify this keyword, only the L3 VXLAN ID and RD will be replaced for the routes from the matching local VPN instance.

Usage guidelines

Application scenarios and operating mechanism for EVPN

In an EVPN-DCI network, use this command to hide the L3 VXLAN IDs of data centers or enable communication between data centers that use different L3 VXLAN IDs.

After you execute this command on an ED, the ED performs the following operations after receiving BGP EVPN routes from a VTEP or remote ED:

1. Matches the route targets of the routes with the import route targets of local VPN instances.

2. Replaces the L3 VXLAN ID and RD of the routes with those of the matching local VPN instance.

3. Advertises the routes to a VTEP or remote ED.

Restrictions and guidelines

After you execute this command, an ED advertises only reoriginated BGP EVPN routes. The original BGP EVPN routes are not advertised.

If the RD of a received BGP EVPN route is identical to the RD of the matching local VPN instance, an ED does not replace the L3 VXLAN ID of the route or reoriginate the route. As a result, the ED does not advertise the route. As a best practice, assign unique RDs to VPN instances on different EVPN gateways and EDs when you use this command.

If you do not specify a route type, this command applies to IP prefix advertisement routes.

Parameters

public-instance: Specifies the public instance.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters.

ip ip-address: Specifies an IPv4 address in dotted decimal notation. If you do not specify an IPv4 address, this command cancels the suppression done on all ARP entries of the public instance or specified MPLS L3VPN instance.

Usage guidelines

Use this command to cancel the ARP mobility event suppression done on IPv4 addresses. After you cancel suppression for an IPv4 address, the IPv4 address can move between sites, and the device advertises ARP information for the IPv4 address. The device still suppresses the IPv4 address if the suppression criteria are met.

If you do not specify the public instance or an MPLS L3VPN instance, this command cancels ARP mobility event suppression for the public instance and all MPLS L3VPN instances.

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.

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.

To modify the RD, first execute the undo route-distinguisher command to remove the original RD.

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.
