Section 10. Configuring Multicast Forwarding

Multicast forwarding enables transmitting packets from either a specific multicast group to a source, or from a nonspecific source to a multicast group.

This section contains the following topics:

Enabling IGMP Snooping

Defining Multicast Bridging Groups

Defining Multicast Forward All Parameters

10.1 Configuring Multicast Forwarding

When IGMP Snooping is enabled globally, all IGMP packets are forwarded to the CPU. The CPU analyzes the incoming packets and determines:

Which ports want to join which Multicast groups.

Which ports have Multicast routers generating IGMP queries.

Which routing protocols are forwarding packets and Multicast traffic.

Ports requesting to join a specific Multicast group issue an IGMP report, specifying that Multicast group is accepting members. This results in the creation of the Multicast filtering database.

To enable IGMP Snooping:

1.Click System > Bridging Config > Multicast Support > IGMP Snooping. The IGMP Snooping Page opens:

Figure 94: IGMP Snooping Page

The IGMP Snooping Page contains the following fields:

Enable IGMP Snooping Status — Indicates if IGMP Snooping is enabled on the device. IGMP Snooping can be enabled only if Bridge Multicast Filtering is enabled. The possible field values are:

Checked — Enables IGMP Snooping on the device.

Unchecked — Disables IGMP Snooping on the device.

VLAN ID — Specifies the VLAN ID.

IGMP Snooping Status — Indicates if IGMP Snooping is enabled on the VLAN. The possible field values are:

Enable — Enables IGMP Snooping on the VLAN.

Disable — Disables IGMP Snooping on the VLAN.

Auto Learn — Indicates if Auto Learn is enabled on the device. If Auto Learn is enabled, the devices automatically learns where other Multicast groups are located. Enables or disables Auto Learn on the Ethernet device.The possible field values are:

Enable — Enables auto learn

Disable — Disables auto learn

Host Timeout — Indicates the amount of time host waits to receive a message before timing out. The default time is 260 seconds.

MRouter Timeout — Indicates the amount of the time the Multicast router waits to receive a message before it times out.
