ip igmp static-group<group-add
Above configuration statically binds the group address to an
interface. Supposing there are always members of the group
on the interface.
To configure the static group 239.10.10.10 on the Vlanl inter-
face is shown below:
ZXR10(config)#interface vlan 1
ZXR10(config-if-vlan1)#ip igmp static-group 239.10.10.10

Configuring IGMP Timer

IGMP boots on the multicast router interface that is connected with
a shared network segment. Select the optimum one as the Querier
of the network segment which is responsible for sending the query
message to obtain the information of the group members.
After sending query messages, the Querier will wait for the mem-
ber report of the receiving mainframe for some time. The duration
is the Max Response Time value carried when sending query mes-
sages. The default value is 10 seconds.
Upon receiving query messages the mainframe member on the
network segment will reduce a random deviation value based on
the maximum response time. It will take the result as its own
response time.
During this period the mainframe member will cancel the receiving
reports of other mainframe. If the mainframe report is not can-
celled then mainframe member will send the mainframe report at
the right time. Therefore, prolonging the max response time will
accordingly increase the waiting chances for the group member
of the network segment. The mainframe member will reduce the
burst rate of multiple mainframe reports on the network segment.
