Use the following fields to configure multicast interfaces that share IGMP, PIM and group permission settings:

Multicast Settings – Interfaces	Description
Name	Enter a name to identify an interface group.
Description	Enter an optional description.
Interface	Add one or more firewall interfaces that belong to the interface group and therefore share multicast group permissions, IGMP settings and PIM settings.
Group Permissions	Specify multicast groups that participate in PIM Any-Source Multicast (ASM) or PIM Source-Specific Multicast (SSM): Any Source—Add a Name to identify a multicast Group that is allowed to receive multicast traffic from any source on the interfaces in the interface group. By default the group is Included in the Any Source list. Deselect Included to easily exclude a group without deleting the group configuration. Source Specific—Add a Name for a multicast Group and Source IP address pair for which multicast traffic is allowed on the interfaces in the interface group. By default the Group and Source pair is Included in the Source Specific list. Deselect Included to easily exclude a Group and Source pair without deleting the configuration.
IGMP	Specify settings for IGMP traffic. IGMP must be enabled for multicast receiver-facing interfaces. Enable—Select to enable the IGMP configuration. IGMP Version—Choose version 1, 2, or 3 to run on the interface. Enforce Router-Alert IP Option—Select to require the router-alert IP option when speaking IGMPv2 or IGMPv3. This must be disabled for compatibility with IGMPv1. Robustness—Choose an integer value to account for packet loss on a network (range is 1 to 7; default is 2). If packet loss is common, choose a higher value. Max Sources—Specify the maximum number of source-specific memberships allowed for the interface group (range is 1 to 65,535 or unlimited). Max Groups—Specify the maximum number of multicast groups allowed for this interface group (range is 1 to 65,535 or unlimited). Query Configuration—Specify the following: Query Interval—Specify the interval at which general queries are sent to all receivers. Max Query Response Time—Specify the maximum time between a general query and a response from a receiver. Last Member Query Interval—Specify the interval between group or source-specific query messages (including those sent in response to leave-group messages). Immediate Leave—Select to leave the group immediately when a leave message is received.
PIM configuration	Specify Protocol Independent Multicast (PIM) settings: Enable—Select to allow this interface to receive and/or forward PIM messages. You must enable for an interface to forward multicast traffic. Assert Interval—Specify the interval between PIM assert messages to elect a PIM Forwarder. Hello Interval—Specify the interval between PIM hello messages. Join Prune Interval—Specify the number of seconds between PIM join messages (and between PIM prune messages). Default is 60. DR Priority—Specify the designated router priority for this interface. BSR Border—Select to use the interface as the bootstrap border. PIM Neighbors—Add the list of neighbors that will communicate using PIM.
