Configuring and Customizing IGMP

Specifying a Query Rate

By default, IGMP sends a group membership query on the interface every 120

seconds.

Specifying zero disables queries only. The router still forwards multicast

datagrams on this circuit.

You can use the BCC or Site Manager to disable queries or specify a query rate

from 0 to 4096 seconds.

Using the BCC

Navigate 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 taken on 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.
