Step-by-Step
Procedure
The following example requires you to navigate various levels in the configuration
hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration
Mode in the CLI User Guide.
To configure IGMP snooping:
1. Configure the bridge domain.
[edit bridge-domains domain1]
user@host# set domain-type bridge
user@host# set interface ge-0/0/1.1
user@host# set interface ge-0/0/2.1
user@host# set interface ge-0/0/3.1
2. Enable IGMP snooping and configure the router to serve as a proxy.
[edit bridge-domains domain1]
user@host# set protocols igmp-snooping proxy
3. Configure the limit for the number of multicast groups allowed on the ge-0/0/1.1
interface to 50.
[edit bridge-domains domain1]
user@host# set protocols igmp-snooping interface ge-0/0/1.1group-limit 50
4. Configure the router to immediately remove a group membership from an interface
when it receives a leave message from that interface without waiting for any other
IGMP messages to be exchanged.
[edit bridge-domains domain1]
user@host# set protocols igmp-snooping immediate-leave
5. Statically configure IGMP group membership on a port.
[edit bridge-domains domain1]
user@host# set protocols igmp-snooping interface ge-0/0/3.1 static group
225.100.100.100
6. Configure an interface to be an exclusively router-facing interface (to receive
multicast traffic).
[edit bridge-domains domain1]
user@host# set protocols igmp-snooping interface ge-0/0/2.1
multicast-router-interface
7. Configure an interface to be an exclusively host-facing interface (to drop IGMP
query messages).
[edit bridge-domains domain1]
user@host# set protocols igmp-snooping interface ge-0/0/1.1 host-only-interface
