1.
enable
2.
configure terminal
3.
interface type number
4.
Do one of the following:

•
ip igmp static-group
{
*
|
group-address
[
source source-address
]}
5.
end

•
For the
type
and
number
arguments, specify an interface that
is connected to hosts.
The first sample shows how to configure an interface on the device
to join the specified group.
Do one of the following:
Step 4
•
ip igmp join-group group-address
•
With this method, the device accepts the multicast packets in
addition to forwarding them. Accepting the multicast packets
prevents the device from fast switching.
•
ip igmp static-group
{
*
|
group-address
