44.9.6 ip igmp join-group
Command:
ip igmp join-group <A.B.C.D >
no ip igmp join-group <A.B.C.D >
Function:
Configure interface to join some IGMP group; the “no ip igmp join-group” command cancels this join
Parameter:
<A.B.C.D>: is group address
Default:
Do not join
Command Mode:
Interface Configuration Mode
Usage Guide:
When the switch is the HOST, the command configures HOST to join some group; that is, if
configuring the interface join-group 224.1.1.1, it will transmit IGMP member report including group
224.1.1.1 when the switch receives IGMP group query transmitted by other switches. Carefully, it is
the diffence between the command and ip igmp static-group command.
Example:
Configure join-group 224.1.1.1 on interface vlan1.
Switch (config)#interface vlan 1
Switch(Config-if-Vlan1)#ip igmp join-group 224.1.1.1
