show evpn instance

 

Syntax

Release Information

Command introduced in Junos OS Release 14.1 for MX series Routers.

Command introduced in Junos OS Release 14.2 for EX Series switches.

Command introduced in Junos OS Release 17.4R1 for QFX10000 switches.

Description

Show Ethernet VPN (EVPN) routing instance information.

When up MEP is configured for an EVPN instance (EVI), the show evpn instance displays a default interface without any configuration with a naming convention as .local..number (for example, .local..8).

Options

noneDisplay brief information about the EVPN routing instance.
brief | extensive(Optional) Display the specified level of output.
backup-forwarder(Optional) Display IP addresses of all the backup designated forwarders for the Ethernet segment.
designated-forwarder(Optional) Display the IP address of the designated forwarder for the Ethernet segment.
esi esi(Optional) Display brief information about the routing instance associated with the specified Ethernet segment identifier (ESI) value, including information on the route distinguisher, bridge domain, IRB, and other information associated with the ESI.
esi-info esi(Optional) Display only the ESI information about the routing instance associated with the specified ESI value.
instance-name(Optional) Display information about the specified routing instance.
neighbor neighbor-address(Optional) Display the IP address of the EVPN neighbor along with information on the connected bridge domain, route distinguisher, and IRB.
neighbor-info neighbor-addres(Optional) Display only the IP address of the EVPN neighbor for a routing instance.

brief

IRB intfs

Statistics on the number of integrated routing and bridging (IRB) interfaces for each routing instance:

  • Total—Total number of IRB interfaces.

  • Up—Number of active IRB interfaces.

  • Nbrs—Number of neighbor IRB interfaces.

brief

MH ESIs

Number of Ethernet segments per routing instance that connect to a multihomed customer site.

brief

Duplicate MAC detection window

The time interval used in detecting a duplicate MAC address.

extensive

Duplicate MAC auto-recovery time

Length of time a device suppresses a duplicate MAC address. At the end of this duration, MAC address updates will resume.

extensive

DF Election preference

Preference value used for the designated forwarder (DF) election:

  • Highest preference—Default DF election preference.

  • Lowest preference—Based on the configuration of the designated-forwarder-preference-least statement at the [edit routing-instance routing-instance-name protocols evpn] hierarchy level.

extensive

Per-instance multicast route label

Label of the multicast route for each routing instance.

none

Total MAC addresses

Total number of local and remote MAC addresses received for each routing instance.

extensive

Default gateway MAC addresses

Number of local and remote MAC addresses serving as a default gateway in this routing instance.

extensive

  • Preference based—DF election based on the configured preference values for an ESI.

extensive

Preference

Preference value for EVPN Multihoming DF election.

extensive

Mode

Mode of operation for each routing instance:

  • single-homed—Default mode and does not require Ethernet segment values to be configured.

  • single-active—EVPN active-standby multihoming mode of operation.

extensive

SH label

Split horizon label used for the active-standby multihoming mode of operation.

extensive
