COMMAND USAGE
◆ Multicast routers send host query messages to determine the interfaces
that are connected to downstream hosts requesting a specific multicast
service. Only the designated multicast router for a subnet sends host
query messages, which are addressed to the link-scope all-nodes
multicast address FF02::1, and uses a time-to-live (TTL) value of 1.
◆ The designated querier is the lowest IP-addressed multicast router on
the subnet.
EXAMPLE
The following shows how to configure the query interval to 100 seconds.
Console(config-if)#ipv6 mld query-interval 100
