Specifying a Query Rate
By default, IGMP sends a group membership query on the interface every 120
seconds.
Specifying 0 disables queries only. The router still forwards multicast datagrams
on this circuit.
You can use the BCC or Site Manager to disable queries or to specify a query rate
from 0 to 4096 seconds.
Using the BCC
Navigate to the IGMP prompt for the interface and enter:
query-rate
<rate>
rate
is the number of seconds from 0 (disabling queries) to 4096.
For example, the following command specifies a query rate of 300 seconds:
igmp/2.2.2.2/3#
query-rate 300
igmp/2.2.2.2/3#
Note:
If another IGMP router on this network has assumed the query role, this
router will not send out queries unless it has not heard of any queries within
the number of seconds specified by the Designated Router Timeout parameter
(see “Specifying a Designated Router Timeout Interval” on page 3-19).
