Configuring MLD Snooping on VLANs
Use the following commands to configure MLD snooping settings on VLANs.
ip igmp snooping querier
version version
Set the IGMP version of the query that the switch sends
periodically. The version range is 1–2.
ip igmp snooping querier
vlan-id
Enable the IGMP snooping querier on the specified
VLAN.
ip igmp snooping querier
election participate vlan-
id
Allow the IGMP snooping querier to participate in the
querier election process when it discovers the presence of
another querier in the VLAN. When this mode is enabled,
if the snooping querier finds that the other querier source
address is more than the snooping querier address, it stops
sending periodic queries. If the snooping querier wins the
election, then it continues sending periodic queries and
the other querier ceases sending queries. Use of election
mode is not recommended when multicast routers are
present in the network.
CTRL + Z Exit to Privileged Exec mode.
