Controls when the router-alert option is required for IGMPv2 and IGMPv3 packet reception and processing.
| vlan | Applies the configuration only to the specified VLAN. If no VLAN is specified, the configuration applies to all VLANs. |
Off—All IGMP packets are received and processed.
By default, the ExtremeXOS software receives and processes all IGMP packets, regardless of the setting of the router-alert option within a packet. The default configuration works with all switches that support the ExtremeXOS software.
IETF standards require that a router accept and process IGMPv2 and IGMPv3 packets only when the router-alert option is set. The on setting for this command sets the ExtremeXOS software to comply with the IETF standards and should be used when the switch will be used with third-party switches that expect IETF compliant behavior.
The following command configures the switch for IETF compliant IGMP packet processing:
configure igmp router-alert receive-required on
This command was first available in ExtremeXOS 12.5.3.
