Multicast

Configuration > Networking > Routing > Multicast

Orchestrator supports multicast routing, a method of sending data from a single IP address to a larger group of recipients.

Up to 60 multicast routes are supported, including up to 30 (S,G) and 30 (*,G) groups.
Up to 1000 sites can participate in the same multicast stream. Aruba recommends up to 200 sites.
All versions of IGMP are supported (IGMPv1, IGMPv2, and IGMPv3).
Multicast routing is supported in Inline Router mode only.

Orchestrator provides four views of multicast status, each accessible by one of the corresponding buttons at the top of the Multicast tab: Summary, Interfaces, Neighbors, and Routes.

Descriptions of fields on the Summary view follow:

Field	Description
Appliance	Name of the appliance (also selected in the left menu) associated with the multicast configuration.
Enable	Indicates whether multicast is enabled.
Rendezvous Point IP	IP address of the centralized, source router distributing the packet of traffic to each router involved in multicast.
Allowed Group	Only IP addresses included in the specified address group can multicast. If no address group is specified, any IP address can multicast. The message Feature is not supported for the appliance displays in this field if the appliance does not support the Allowed Group feature.

Click the edit icon to enable or disable multicast, add an interface for multicast, or edit an existing interface.

Multicast Dialog Box

From the Summary, Interfaces, Neighbors, or Routes view on the Multicast tab:

Click the edit icon next to the appliance for which you want to set up multicast.

The Multicast dialog box opens.
Move the Enable Multicast toggle to the right to enable multicast.
In the Rendezvous Point IP Address field, enter the appropriate IP address.
In the Allowed Group field, select an available address group from the drop-down list or enter a new address group. All IP addresses included in the specified address group will be allowed to multicast. This field is not displayed if the appliance does not support the Allowed Group feature. Address group names can include letters, numbers, periods, underscores, or hyphens.

IMPORTANT: The address group you specify in the Address Group field must be valid. If you enter a new address group, ensure that you also create and set it up on the Address Groups tab (Configuration > Templates & Policies > ACLs > Address Groups). If the new address group remains invalid, no IP addresses will be allowed to multicast.

Interfaces

Field	Description
Interface	Name of the interface you want to connect.
PIM Enabled	Indicates whether Protocol Independent Multicast is enabled. This allows routers to communicate through the unidirectional shared trees within multicast through the shortest path.
IGMP Enabled	Indicates whether Internet Group Management Protocol is enabled. This establishes the other routers in the multicast group.
DR Priority	Designated router priority of the given interface.
DR Router IP	IP address of the designated router within your network.

To add an interface:

Click Add.

The Add Interface dialog box opens.
Select the desired interface from the Interface drop-down list.
Select the Enable PIM check box if you want to enable it.
Select the Enable IGMP check box if you want to enable it.
Click Add.

Neighbors

Field	Description
Interface	Name of the interfaces you want to connect.
Neighbor DR Priority	Designated router priority of the neighbor.
Neighbor IP	IP address of the neighbor.

Routes

Field	Description
Source	Transmitter of the multicast data.
Group	IP address of the multicast group.
Incoming Interface	Interface that receives inbound traffic.
Outgoing Interfaces	Interface that receives outbound traffic.

On the Multicast tab, you can click Export CSV to export a spreadsheet of the multicast report. You can also click the refresh button to update information displayed on the tab.
