Level: 8
IGMP Snooping can be configured to one of the three versions: v1, v2 and v3. When
it is configured to v1, it means the IGMP Snooping will run in v1 compatibility mode.
When it is configured to v2, it means the IGMP Snooping will run in v2 compatibility
mode. Version 3 is just the IGMP Snooping running version.
In spite of the version configured on the switch, IGMP Snooping will process
IGMPv1/v2/v3 report/leave packet as defined in RFC 3376 (IGMPv3). The difference
behaves in different version is the IGMP general query transmitting and the querier
electing when the querier state is enabled.
General Query Transmit:
• When configured to version 1, IGMP Snooping will only send IGMPv1 general
query packet.
• When configured to version 2, IGMP Snooping will only send IGMPv2 general
query packet.
• When configured to version 3, IGMP Snooping will only send IGMPv3 general
query packet.
Querier Elect:
• When configured to version 1, IGMP Snooping will always act as querier, and
will not initiate a new Querier electing no matter what the IGMP query packet it
received.
• When configured to version 2 or version 3, IGMP Snooping will initiate a new
querier electing if any IGMP v2 or v3 query packet is received. When receiving
an IGMP v1 Query packet, IGMP Snooping won't initiate a new querier
electing.
To verify your configuration, you can use show ip igmp snooping.
