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.

vlan name

Display IGMP snooping information only for the specified VLAN.

Required Privilege Level

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
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)
