configure igmp router-alert receive-required
Description
Controls when the router-alert option is required for IGMPv2 and IGMPv3 packet reception and processing.
Syntax Description
| vlan | Applies the configuration only to the specified VLAN. If no VLAN is specified, the configuration applies to all VLANs. |
Default
Off—All IGMP packets are received and processed.
Usage Guidelines
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.
Example
The following command configures the switch for IETF compliant IGMP packet processing:
configure igmp router-alert receive-required on
