MLD Snooping Commands

If the MLD Querier election mechanism is enabled, the MLD Snooping querier
supports the standard MLD Querier election mechanism specified in RFC2710
and RFC3810.
If MLD Querier election mechanism is disabled, MLD Snooping Querier delays
sending General Query messages for 60 seconds from the time it was enabled.
During this time, if the switch did not receive an IGMP query from another Querier
- it starts sending General Query messages. Once the switch acts as a Querier, it
will stop sending General Query messages if it detects another Querier on the
VLAN. In this case, the switch will resume sending General Query messages if it
does hear another Querier for Query Passive interval that equals to
<Robustness>*<Query Interval> + 0.5*<Query Response Interval).
See the ipv6 mld robustness , ipv6 mld query-interval , and ipv6 mld
query-max-response-time commands for configurations of these parameters.
It is recommended to disable MLD Querier election mechanism if there is an IPMv6
Multicast router on the VLAN.
Example
The following example disables MLD Snooping Querier election on VLAN 1:
switchxxxxxx(config)# no ipv6 mld snooping vlan 1 querier election
42.6 ipv6 mld snooping vlan querier version
To configure the IGMP version of an IGMP querier on a specific VLAN, use the ipv6
mld snooping vlan querier version command in Global Configuration mode. To
return to the default, use the no form of this command.
