IP Multicasting

How to setup IGMP snooping in your switch?

Figure 1: IGMP and IGMP snooping

IGMP snooping is designed for application with deployment of multicast traffic.

It operates on the underlying IGMP mechanism where a layer two switch

passively listens to the IGMP Query, Report and Leave (IGMP version 2)

packets transmitted between the IGMP router and clients, and collects passing

IGMP messages. Also, the switch records the message’s group registration

information and configures multicasting information accordingly. If the

multicast group information is unknown (not recorded on the switch), the

switch discards that multicast traffic. Only the registered clients that join the

group will receive multicast stream from the IGMP router. Thus this

significantly reduces the multicast traffic forwarded down to the clients.

Another advantage of IGMP snooping is that it allows the intermediate

switches to learn multicast group information without the need of configuring

them manually.

Configuration of IGMP snooping using web

In this example, we enable the IGMP function on the GS-4024 device (or it has

to be a ZyXEL L3 Switch) and connect it to a multimedia server. Also, we

enable IGMP snooping function on the ES-3124 Switch or other ZyXEL L2

Switch which support IGMP Snooping to connect to the multimedia clients.

Figure 2: IGMP snooping Example

Step one: In the GS-4024 GUI, click the IP Application ÆIGMP. Here, both

versions of the the IGMP function can be enabled ( IGMP-v1 and IGMP-v2). At

this case, we enabled IGMPv2 for both IP Domain.
