EVPN MPLS Commands

When the ARP cache is disabled on a access circuit, It does not reply to any ARP arriving on this port from the cache. It withdraws all MAC/IPs configured/learned on this access circuit and removes the MAC/IP entry for this AC from the local ARP cache.

It also makes sure that on withdrawing the MAC/IP route, the MAC does not become unknown. If all routes for this MAC are being withdrawn because of this command, then It advertises a MAC-only route. This is done so that the MAC does not become unknown and only the cache functionality becomes disabled.

Use the no form of this command to enable ARP cache for MAC/IP.

Note: On enabling the cache, an IP will be in conflict, then the cache enable will fail. The conflict has to be manually removed and then the cache enabled.

Note: When encapsulation default is configured under L2 subifp , then arp-packets will not be uplifted.

Note: Not applicable for the AC port which is mapped with ELINE/Xconnect Service.

Command Syntax

arp-cache disable

no arp-cache disable

Parameters

None

Default

By default, the arp-cache option is enabled.

arp-nd flood-suppress

Use this command to completely restrict the flood of ARP/ND packets towards remote PEs or other Access Circuit

mac-holdtime

Use this command to set the MAC hold time for a MAC/IP or MAC.

The feature holds the MAC in hardware until BGP has withdrawn from the neighbors. This helps to reduce the flooding to other access ports.

This setting applies when the L2 Subifp is shut down, the physical port on which the access port is down, or the access port is removed from the VNID using the no form of the map vnid command.

When the MAC hold time is configured as -1, then the MAC is not removed from the hardware and is also not withdrawn from EVPN BGP.

Use the no form of this command to remove the MAC hold time for the MAC/IP or MAC.

Note: When a MAC is moved to discard state, traffic to and from this MAC is discarded. This is applicable only on statically configured MAC/MAC-IPs.

Command Syntax

mac-holdtime <-1-300>

no mac-holdtime

Parameters

<-1-300>

MAC hold time in seconds. Specify -1 to "never expire".

Default

The default holdtime for mac is 3 seconds.

Command Mode

Note: When configured in both modes, then the ACC_IF mode value takes preference for that access port.

Applicability

This command was introduced in OcNOS version 4.0.

nd-cache disable

Use this command to disable ND cache for MAC/IPv6.

When the ND cache is disabled on an Access Circuits, It does not reply to any ND arriving on this port from the cache. It withdraws all MAC/IPs configured/learned on this Access Circuit and removes the MAC/IP entry for this AC from the local ND cache.

It also makes sure that on withdrawing the MAC/IP route, the MAC does not become unknown. If all routes for this MAC are being withdrawn because of this command, then it advertises a MAC-only route. This is done so that the MAC does not become unknown and only the cache functionality becomes disabled.

Use the no form of this command to enable ND cache for MAC/IPv6.

Note: On enabling the cache, an IP will be in conflict, then the cache enable will fail. The conflict has to be manually removed and then the cache enabled.

Note: Not applicable for the AC port which is mapped with ELINE/Xconnect Service.

nd-cache disable

no nd-cache disable

Parameters

None

Default

By default, the nd-cache option is enabled.

Command Mode

Applicability

This command was introduced in OcNOS version 4.0.

show bgp l2vpn evpn

Use this command to display details about Layer 2 Virtual Private Network (L2VPN) Ethernet Virtual Private Network (EVPN) routes.

Note: A BGP EVPN route update received for an unreachable IP address is also listed by this command and as a best route. This is because the next hop tracking feature is not supported for the EVPN address family. However, the tunnel to this IP address is shown in unresolved state by the show nvo vxlan tunnel output.

Note: An E-tag (Ethernet tag) can have the value of zero/VID/VNID based on the use case. An E-tag can go up to 32 bits and no restrictions are noted in the RFC. Since an E-tag can have different values, it should not be compared with the label/VNID.

MH-PE2#

show evpn load-balance

Use this command to display ESI information in Single-Active or Port-Active mode. It assists the user in identifying whether the local device is in Active or Standby mode and understanding which election algorithm is used for ESI. In remote devices, information will only be displayed for ELINE services.

This command is used to debug and understand if the election process is occurring correctly. The commands on multi-homed devices are symmetric, and they provide insights into the election algorithm used for the DF election.

Command Syntax

show evpn load-balance (port-active | single-active)

Parameters

None

Command Mode

Exec mode

Applicability

This command was introduced before OcNOS version 6.4.1 and underwent modifications in the OcNOS version 6.4.2

Example

The following example displays ESI information using the show evpn load-balance port-active and show evpn load-balance single-active commands.

service-carving

Use this command to provide the flexibility to select the Designated Forwarder (DF) election algorithm based on preference based or modulo-based DF election.

Use no form of this command to disable service-carving.

For more information, refer to the service-carving command in the EVPN Active-Standby section in the OcNOS Key Feature document, Release 6.4.1.

service-carving ac-driven

Use this command to enable the AC-influenced method for any selected Designated Forwarder (DF) algorithm.

Enabling the ac-driven method allows the Designated Forwarder (DF) algorithm to be influenced by the Attachment Circuits (AC’s) associated with a specific Ethernet Segment (ES). This means that the DF selection is based on the AC’s characteristics and conditions, such as whether an AC is operational UP, mapped, or unmapped on the ESI.

Use no form of this command to disable the AC-influenced method for any selected Designated Forwarder (DF) algorithm.

For more information, refer to the service-carving weight command in the EVPN Active-Standby section in the OcNOS Key Feature document, Release 6.4.2.

service-carving weight

Use this command to specify a preference value when the preference-based Designated Forwarder (DF) election algorithm is selected. This preference value determines the priority of the local PE device to become the DF for a particular Ethernet segment.

Use no form of this command to replace the preference weight value and choose the default preference value.

For more information, refer to the service-carving weight command in the EVPN Active-Standby section in the OcNOS Key Feature document, Release 6.4.1.

tunnel-select-policy

Use this command to associate tunnel-policy to an EVPN instance and to a mac-vrf. This will be used while selecting transport for EVPN service. In particular, an EVPN instance could be either an ELINE or ELAN type and may also multi-homing also enabled.

Use the no parameter with this command to un-configure tunnel-policy from the EVPN instance.

Please refer MPLS Service Mapping Configuration for Tunnel-policy Name configuration.

Command Syntax

tunnel-select-policy NAME

no tunnel-select-policy

Parameters

NAME

Name of tunnel-policy

Command Mode

EVPN MPLS Config mode and MAC_VRF MODE

Note:

Applicability

This command was introduced in OcNOS version 4.1 but the support for this CLI under mac-vrf mode is introduced in OcNOS-SP version 4.2.

Examples

#configure terminal

(config)#mac vrf vrf1

(config-vrf)# tunnel-select-policy policy1

(config-vrf)#end

(config)# evpn mpls id 1001

(config-evpn-mpls)# tunnel-select-policy policy2

(config-evpn-mpls)# end

(config)# evpn mpls id 10 xconnect target-mpls-id 20

(config-evpn-mpls)# tunnel-select-policy policy3

(config-evpn-mpls)# end
