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· MAC address advertisement is disabled, and advertised MAC addresses are withdrawn.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

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 a VSI EVPN instance.

evpn m-lag group

Use evpn m-lag group to enable EVPN M-LAG and specify the virtual VTEP address.

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

Syntax

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.

Usage guidelines

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

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

To modify the virtual VTEP address, you must first delete the original virtual VTEP address.

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

Related commands

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 that uses a direct peer link. You do not need to execute this command on an M-LAG system that uses a VXLAN tunnel as the peer link. In such an M-LAG system, a VTEP uses the source IP address of the peer link as the next hop of routes for single-armed ACs to ensure correct traffic forwarding.

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.

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.

<Sysname> system-view

[Sysname] evpn m-lag local 2.2.2.2 remote 3.3.3.3

Usage guidelines

If you specify the local VTEP address for EVPN M-LAG, the device advertises the following BGP EVPN routes.

· IMET route in which the originator IP address is the local VTEP address.

· IP prefix advertisement route in which the next hop is the local VTEP address.

· MAC/IP advertisement route in which the next hop is the local VTEP address. This route is advertised for each MAC address entry or ARP entry learned on a local interface attached to a singlehomed peer device.

The device also advertises BGP EVPN routes that carry the virtual VTEP address of the M-LAG system. As a result, a peer VTEP sets up the following VXLAN tunnels with the device:

· A VXLAN tunnel sourced from the IP address of the peer VTEP and destined for the local VTEP address of the device. This tunnel is used to forward broadcast, unknown-unicast, and multicast (BUM) traffic and known unicast traffic for which the outgoing interface is an AC-attached interface facing a singlehomed device.

· A VXLAN tunnel sourced from the IP address of the peer VTEP and destined for the virtual VTEP address. This tunnel is used to forward BUM traffic and known unicast traffic for which the outgoing interface is an M-LAG interface.

If no peer device is singlehomed to an AC-attached interface of the M-LAG system, the VXLAN tunnel set up with the local VTEP address does not forward service traffic. To save tunnel resources, allow only MAC/IP advertisement routes to carry the local VTEP address. Then, the IMET routes and IP prefix advertisement routes advertised by the device will not carry the local VTEP address. If the device does not learn a MAC address entry or ARP entry on a local interface attached to a singlehomed peer device, it will not advertise a MAC/IP advertisement route in which the next hop is the local VTEP address. As a result, a peer VTEP will not set up a VXLAN tunnel with the local VTEP address.

Parameters

group-ipv4: Specifies the IPv4 virtual ED address.

group-ipv6: Specifies the IPv6 virtual ED address.

Usage guidelines

For high availability and load sharing, you can deploy two EDs at a data center. To virtualize the redundant EDs into one device, you must configure the same virtual ED address on them. The redundant EDs use the virtual ED address to establish tunnels with VTEPs and remote EDs.

Redundant EDs cannot provide access service for local VMs. They can act only as EDs. For correct communication, do not redistribute external routes on only one of the redundant EDs. However, you can redistribute the same external routes on both EDs.

On a redundant ED, the virtual ED address must be the IP address of a loopback interface, and it cannot be the BGP peer IP address of the ED.

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

If you execute the undo bgp command to disable the BGP instance of the EVPN address family, the evpn edge group setting will also be deleted. Make sure you are fully aware of the impact of the undo bgp command when you use it on a live network.

Parameters

mac-address: Specifies a MAC address in H-H-H format. Do not specify a multicast MAC address, broadcast MAC address, or all-zeros MAC address.

Usage guidelines

The EVPN global MAC address is used only by VSI interfaces associated with an L3 VXLAN ID.

For a VSI interface associated with an L3 VXLAN ID, the MAC address assigned to it by using the mac-address command takes precedence over the EVPN global MAC address.

Do not use a reserved MAC address as the EVPN global MAC address.

Usage guidelines

If a distributed EVPN gateway has downstream VTEPs attached, the gateway advertises ARP information for gateway interfaces through IP prefix advertisement routes. Because the VTEPs do not have gateway configuration, they cannot learn the ARP information for the gateway interfaces or forward traffic to the gateway. For the VTEPs to learn ARP information for the gateway interfaces, enable the distributed EVPN gateway to advertise ARP information for the gateway interfaces through MAC/IP advertisement routes.

Predefined user roles

network-admin

Parameters

detect-cycle detect-time: Specifies the ARP 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 ARP mobility suppression threshold, which is the number of ARP 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 ARP entry is suppressed. After the suppression time expires, the ARP 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 ARP 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 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 the VTEPs. This feature allows an IP address to move at most four times from a site within 180 seconds. If an IP address moves more than four times within 180 seconds, the VTEP at the site will suppress the excess ARP mobility events and will not advertise ARP information for the IP address.

After you execute the undo evpn route arp-mobility suppression command, 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 the following networks:

· EVPN VXLAN network enabled with ARP flood suppression.

· EVPN VXLAN network configured with distributed VXLAN IP gateways.

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.

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

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.

Views

VSI interface view

Predefined user roles

network-admin

Usage guidelines

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

· The VTEPs have established BGP EVPN neighbor relationships.

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

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

· Remote-MAC address learning is disabled.

· Local proxy ND 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 process occurs:

1. VM 1 sends an NS packet.

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

3. VTEP 2 forwards the NS packet, and VM 2 replies to VTEP 1.

4. VTEP 2 forwards the NA packet sent by VM 2 without learning the MAC address of VM 2 because EVPN is disabled from learning MAC addresses from ND 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 NS packet proxy on VSI-interface 2 of VTEP 2. When receiving the NS packet sent by VTEP 1, VTEP 2 forwards it and sends an NS packet sourced from VSI-interface 2 simultaneously, and VM 2 replies to both NS packets. Then, VTEP 2 learns the MAC address of VM 2 from the NA packet sent to 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.

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.

As a best practice, set the PVID to 4094 on the peer-link interfaces. If you fail to do so, an M-LAG member device might set the outer VLAN ID matched by an AC to the PVID of its peer-link interface. This error will affect forwarding of the underlay traffic whose VLAN ID is VXLAN ID%4094 + 1.

Usage guidelines

If you configure an L3 VXLAN ID on a distributed EVPN gateway, the gateway automatically creates a VSI for the L3 VXLAN ID. You cannot enter the view of such a VSI to configure settings on it.

This command enables the device to collect incoming and outgoing traffic statistics for the automatically created VSIs. You can use the display l2vpn vsi verbose command to view the traffic statistics and use the reset l2vpn statistics vsi command to clear the traffic statistics.

Parameters

vxlan-id: Specifies a VXLAN ID. The value range for this argument is 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.

Default

The device can select a default route for forwarding after performing route recursion.

Views

BGP EVPN address family view

Predefined user roles

network-admin

Parameters

route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters. The device will ignore default routes when performing route recursion for the routes that match the if-match interface criterion in the routing policy. If you do not specify a routing policy or the specified routing policy does not exist, the device ignores default routes when performing route recursion for all received BGP routes.

Usage guidelines

CAUTION:

After you execute this command, VXLAN tunnels might be reestablished, and transient VXLAN traffic loss might occur. As a best practice, enable BGP EVPN route reception and advertisement again after you execute this command.

By default, the device selects a default route to forward traffic if only the default route is obtained after BGP route recursion. If the default route does not point to the desired next hop, traffic forwarding will fail.

To resolve this issue, enable the device to ignore default routes in route recursion. If only the default route is obtained after route recursion is performed for a BGP route, that BGP route becomes invalid, and other BGP routes with the same prefix are selected for forwarding.

Enable this feature if multiple links exist between the device and a destination IP address. If one of the links fail, traffic will be switched to the other available links instead of being incorrectly forwarded based on a default route.

Parameters

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

ipv4-address: Specifies a peer by its IPv4 address.

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.

Usage guidelines

When you use this command and the peer next-hop-local command, follow these restrictions:

· The peer next-hop-invariable command is exclusive with the peer next-hop-local command. You can execute only one of these commands for a peer or peer group.

· If you have executed the peer next-hop-invariable command for a peer group, you cannot execute the peer next-hop-local command for any peer in the peer group.

· When you execute the peer next-hop-local command for a peer group whose members already have the peer next-hop-invariable setting, the peer next-hop-local command overwrites that setting.

The next hop in BGP EVPN routes is the IP address of the originating VTEP. By default, the device replaces the next hop of IBGP routes with its address when advertising the routes to an EBGP peer. If the device is a transport network device, it will modify the next hop of BGP EVPN routes. For VTEPs to learn one another's IP address, you must configure the device to not change the next hop of routes advertised to EBGP peers.

replace-rt: Replaces the L3 VXLAN ID, RD, and route targets of BGP EVPN routes 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.

Usage guidelines

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 or route targets.

After you execute this command on an ED, the ED performs the following operations after receiving BGP EVPN routes:

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

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

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

After you execute this command, an ED advertises only modified BGP EVPN routes. The original BGP EVPN routes are not advertised. To advertise the original BGP EVPN routes, use the peer advertise original-route command.

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 and route targets of the route or regenerate 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 if you use the peer re-originated command.

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

Usage guidelines

This command enables an ED to use its router MAC address to replace the router MAC address of routes received from and advertised to a peer or peer group in the local data center. The router MAC replacement process is as follows:

· For routes received from the peer or peer group, the ED performs router MAC replacement and advertises the routes to remote EDs.

· For routes received from a remote data center, the ED performs router MAC replacement and advertises the routes to the peer or peer group.

After you cancel suppression for a MAC address, the MAC address can move between sites, and the device advertises the MAC address entry. The device still suppresses the MAC address if the suppression criteria are met.

Examples

# Cancel the MAC mobility event suppression done on 1-1-1 of VSI vpna.

<Sysname> reset evpn route mac-mobility suppression vsi vpna mac 1-1-1

Related commands

display evpn route mac-mobility

reset evpn route nd-mobility suppression

Use reset evpn route nd-mobility suppression to cancel ND mobility event suppression.

Syntax

reset evpn route nd-mobility suppression [ public-instance | vpn-instance vpn-instance-name [ ip ipv6-address ] ]

Predefined user roles

network-admin

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 ipv6-address: Specifies an IPv6 address. If you do not specify an IPv6 address, this command cancels suppression on all ND entries of the public instance or specified MPLS L3VPN instance.

Usage guidelines

Use this command to cancel the ND mobility event suppression done on IPv6 addresses. After you cancel suppression for an IPv6 address, the IPv6 address can move between sites, and the device advertises ND information for the IPv6 address. The device still suppresses the IPv6 address if the suppression criteria are met.

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

Examples

# Cancel the ND mobility event suppression done on 1::1 of VPN instance vpna.

<Sysname> reset evpn route nd-mobility suppression vpn-instance vpna ip 1::1

route-distinguisher

Use route-distinguisher to configure an RD for an EVPN instance or the public instance.

Use undo route-distinguisher to restore the default.

Syntax

In public instance view:

route-distinguisher route-distinguisher

undo route-distinguisher

In VSI EVPN instance view:

route-distinguisher { route-distinguisher | auto [ router-id ] }

undo route-distinguisher

Default

No RD is configured for an EVPN instance or the public instance.

Views

Public instance view

VSI EVPN instance view

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 or PE 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 of the public instance, first execute the undo route-distinguisher command to remove the original RD.

Examples

# Configure 22:1 as the RD of the EVPN instance on VSI aaa.

<Sysname> system-view

[Sysname] vsi aaa

[Sysname-vsi-aaa] evpn encapsulation vxlan

[Sysname-vsi-aaa-evpn-vxlan] route-distinguisher 22:1

rr-filter

Use rr-filter to create a route reflector (RR) reflection policy.

Use undo rr-filter to restore the default.

Syntax

rr-filter ext-comm-list-number

undo rr-filter

Default

An RR does not filter reflected BGP EVPN routes.

Views

BGP EVPN address family view

Predefined user roles

network-admin

Parameters

ext-comm-list-number: Specifies an extended community attribute list by its number in the range of 1 to 65535.

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.

Examples

# Configure a reflection policy for the device to reflect BGP EVPN routes that match extended community attribute list 10.

snmp-agent trap enable evpn

Use snmp-agent trap enable evpn to enable SNMP notifications for EVPN.

Syntax

snmp-agent trap enable evpn [ mac-mobility-suppression ]

undo snmp-agent trap enable evpn [ mac-mobility-suppression ]

Views

System view

Default

SNMP notifications are disabled for EVPN.

Predefined user roles

network-admin

Parameters

mac-mobility-suppression: Specifies the MAC mobility suppression notification.

Usage guidelines

If SNMP notifications are enabled for EVPN, a MAC mobility suppression notification is sent to SNMP module after the MAC mobility suppression threshold is reached. For SNMP notifications to be sent correctly, you must also configure SNMP on the device. For more information about SNMP configuration, see Network Management and Monitoring Configuration Guide.

If you do not specify any parameter, all EVPN notifications are enabled or disabled.

Examples

# Enable SNMP notifications for EVPN.

<Sysname> system-view

[Sysname] snmp-agent trap enable evpn

vpn-route cross multipath

Use vpn-route cross multipath to enable ECMP VPN route redistribution.

Use undo vpn-route cross multipath to disable ECMP VPN route redistribution.

Syntax

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 or PE 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 or PE sets the export targets for BGP EVPN routes before advertising the routes to remote VTEPs or PEs. The VTEP or PE checks the export targets of BGP EVPN routes from remote VTEPs or PEs 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 the EVPN instance on VSI aaa.

<Sysname> system-view

[Sysname] vsi aaa

[Sysname-vsi-aaa] evpn encapsulation vxlan
