Juniper ACX2000 Configuration Guide

When you configure static groups on an interface on which you want to receive multicast
traffic and your network is operating in source-specific multicast (SSM) mode, you can
specify that certain multicast source addresses be excluded.
By default the multicast source address configured in a static group operates in include
mode. In include mode the multicast traffic for the group is accepted from the source
address configured. You can also configure the static group to operate in exclude mode.
In exclude mode the multicast traffic for the group is accepted from any address other
than the source address configured.
If a source address is specified in a multicast group that is statically configured, the IGMP
version on the interface must be set to IGMPv3. IGMPv2 is the default value.
In this example, you exclude address 10.0.0.2 as a source for group 233.252.0.1.
1. On the DR, configure a multicast static group to operate in exclude mode by including
the exclude statement and specifying which IPv4 source address to exclude.
[edit protocols igmp]
user@host# set interface fe-0/1/2 static group 233.252.0.1 exclude source 10.0.0.2
2. After you commit the configuration, use the show configuration protocol igmp command
to verify the IGMP protocol configuration.
user@host> show configuration protocol igmp
interface fe-0/1/2.0 {
version 3;
static {
group 233.252.0.1 {
exclude;
source 10.0.0.2;
}
}
}
3. After you have committed the configuration and the source is sending traffic, use the
show igmp group detail command to verify that static group 233.252.0.1 has been
created and that the static group is operating in exclude mode.
user@host> show igmp group detail
Interface: fe-0/1/2
Group: 233.252.0.1
