show igmp snooping evpn status

Syntax

Description

Display Layer 2 multicast IGMP snooping information for the EVPN instances on devices in an EVPN network.

By default, this command displays brief output for all EVPN instances with IGMP snooping enabled for one or more VLANs.

Options

(brief | detail)

Display brief information (the default output level) or more detailed information.

When you enable the optimized intersubnet multicast (OISM) feature, the detail option provides more about the different bridge domains (VLANs) OISM uses in the EVPN network. You also see whether enhanced OISM is enabled to support multicast traffic over data center interconnect (DCI) seamless stitching.

vlan name

Display IGMP snooping information only for the specified VLAN.

Output Fields

Table 1: show igmp snooping evpn status Output Fields
Field Name Field Description

Output Level

Bridge-Domain

Bridge domain or VLAN with IGMP snooping enabled.

all

DCI Status

IGMP snooping on a DCI seamless stitching interconnect gateway (iGW) device to support optimized multicast traffic over the interconnection. This field displays:

  • Yes—On the iGW devices in a DCI-enabled EVPN data center.

  • No—On non-iGW devices in a DCI-enabled EVPN data center, or any devices in an EVPN data center without DCI enabled.

detail

External VLAN

OISM external VLAN:

  • Yes—OISM is enabled and uses this VLAN to send multicast traffic to an external multicast receiver or receive multicast traffic from an external multicast source.

  • No—OISM is not enabled, or OISM is enabled but doesn't use this VLAN to exchange traffic with an external multicast domain.

An OISM external VLAN must be different from the SBDs or OISM revenue VLANs in the EVPN fabric. See OISM Bridge Domains (VLANs) for details.

detail

Instance

EVPN instance (EVI) name.

all

Mode

Configured multicast replication mode:

  • Enhanced OISM—Enhanced OISM (the asymmetric bridge domains OISM model, also called the bridge domains not everywhere [BDNE] version).

  • Default—Any other mode besides enhanced OISM, including regular OISM (the symmetric bridge domains OISM model, also called the bridge domains everywhere [BDE] version).

To set the multicast mode in EVPN networks, you use the irb (local-only | local-remote | oism | enhanced-oism) statement at the [edit forwarding-options multicast-replication evpn] hierarchy level. See multicast-replication for details.

default (brief)

OISM

OISM status—Enabled or not enabled.

all

SMET enabled

Selective multicast Ethernet tag (SMET) forwarding using EVPN Type 6 routes—Yes (enabled) or No (not enabled).

default (brief)

Supplementary BD

OISM supplemental bridge domain (SBD):

  • Yes—OISM is enabled and uses this bridge domain or VLAN as an OISM SBD.

  • No—OISM is not enabled, or OISM is enabled but doesn't use this bridge domain or VLAN as an OISM SBD.

An OISM SBD must be a VLAN that is different from any OISM revenue VLANs or external VLANs in the EVPN network. See OISM Bridge Domains (VLANs) for details.

detail

VN Identifier

Virtual network identifier (VNI) corresponding to this VLAN

all

Sample Output

show igmp snooping evpn status (Regular OISM enabled)

show igmp snooping evpn status (MAC-VRF EVPN instance and enhanced OISM enabled)

show igmp snooping evpn status vlan VLAN-300 detail (default-switch EVPN instance, regular OISM enabled, and specified VLAN is the OISM SBD)

show igmp snooping evpn status detail (with enhanced OISM over DCI seamless stitching on interconnect gateway device and other leaf device)

Release Information

Command introduced in Junos OS Release 18.2R1.
