Description
Use the
igmp static-group
command to configure the current interface to be a statically connected
member of the specified multicast group or multicast source and group.
Use the
undo igmp static-group
command to restore the system default.
By default, an interface is not a static member of any multicast group or multicast source and group.
If the specified multicast address is in the SSM multicast address range, you must specify a multicast
source address at the same time; otherwise IGMP routing table entries cannot be established. There is
no such a restriction if the specified multicast group address is not in the SSM multicast address range.
Examples
# Configure VLAN-interface 1 to be a statically connected member of multicast group 224.1.1.1.
[Sysname] interface Vlan-interface1
[Sysname-Vlan-interface1] igmp static-group 224.1.1.1
# Configure VLAN-interface 1 to be a statically connected member of multicast source and group

[Sysname] interface Vlan-interface1
[Sysname-Vlan-interface1] igmp static-group 232.1.1.1 source 192.168.1.1
