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:
<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:
console(config)# no ipv6 mld snooping vlan 1 querier
election
ipv6 mld snooping vlan querier version
Use the ipv6 mld snooping vlan querier version Global Configuration mode
command to configure the IGMP version of an IGMP querier on a specific
VLAN. Use the no form of this command to return to the default version.
Syntax
ipv6 mld snooping vlan vlan-id querier version {1 | 2}
no ipv6 mld snooping vlan vlan-id querier version
Parameters
• vlan-id —Specifies the VLAN.
