ipv6 mld snooping querier
Use this command to enable MLD querier operation on a subnet (VLAN) when no
multicast routing protocol is configured in the subnet (VLAN). When enabled, the MLD
Snooping querier sends out periodic MLD queries for all interfaces on that VLAN.
Use the no variant of this command to disable MLD querier configuration.
Syntax ipv6 mld snooping querier
no ipv6 mld snooping querier
Mode Interface Configuration for a specified VLAN interface.
Usage This command can only be configured on a single VLAN interface - not on multiple VLANs.
The MLD Snooping querier uses the 0.0.0.0 Source IP address because it only masquerades
as an MLD querier for faster network convergence.
The MLD Snooping querier does not start, or automatically cease, the MLD Querier
operation if it detects query message(s) from a multicast router. It restarts as an MLD
Snooping querier if no queries are seen within the other querier interval.
Do not enable MLD Snooping querier if you have already enabled MLD on your device.
Do not enable MLD Snooping querier on your device and then enable MLD afterwards.
Example
awplus# configure terminal
awplus(config)# interface vlan2
awplus(config-if)# ipv6 mld snooping querier
