Configure IGMP join groups

You can configure an interface to be a member of a multicast group.

Configuring the Firewall Threat Defense device to join a multicast group, upstream routers maintain multicast routing table information for that group and keep the group's paths active.

Note	Refer to Configure IGMP static groups if you want to forward multicast packets for a specific group to an interface without the Firewall Threat Defense device accepting those packets as part of the group.

Procedure

Step 1

Choose Devices > Device Management, and edit the Firewall Threat Defense device.

Step 2

Choose Routing > Multicast Routing > IGMP.

Step 3

On Join Group, click Add or Edit.

Use the Add IGMP Join Group parameters dialog box to configure the Firewall Threat Defense device to be a member of a multicast group. Use the Edit IGMP Join Group parameters dialog box to change existing parameters.

Note	The IGMP Join Group enables PIM to send Join requests to sources or to the Rendezvous Point (RP) if the firewall with this command is the PIM Designated Router (DR) on that interface.

Step 4

Configure the following options:

From the Interface drop-down list, choose the interface you want to be a member of a multicast group. If you are editing an existing entry, you cannot change the value.
From the Join Group drop-down list, choose the multicast group to which you want to assign the interface, or click Plus to create a new multicast group. Refer to Creating Network Objects for the procedure.
