You can create IGMP static group membership to test multicast forwarding without a
receiver host. When you enable IGMP static group membership, data is forwarded to an
interface without that interface receiving membership reports from downstream hosts.
The router on which you enable static IGMP group membership must be the designated
router (DR) for the subnet. Otherwise, traffic does not flow downstream.
When enabling IGMP static group membership, you cannot configure multiple groups
using the ,
group-count group-increment
if the all option is specified as the IGMP interface.
Class-of-service (CoS) adjustment is not supported with IGMP static group membership.
In this example, you create static group 233.252.0.1.
On the DR, configure the static groups to be created by including the
1.
and statement and specifying which IP multicast address of the group to be
group
created. When creating groups individually, you must specify a unique address for
each group.
[edit protocols igmp]
user@host# set interface fe-0/1/2 static group 233.252.0.1
After you commit the configuration, use the
2.
to verify the IGMP protocol configuration.
user@host> show configuration protocol igmp
interface fe-0/1/2.0 {
static {
group 233.252.0.1 ;
}
}
After you have committed the configuration and the source is sending traffic, use the
3.
command to verify that static group 233.252.0.1 has been created.
