Create a PIM feature template to configure PIM parameters.

1. From the Cisco SD-WAN Manager menu, choose Configuration > Templates.

2. Click Device Templates.

   In Cisco Catalyst SD-WAN Control Components Release 20.7.x and earlier releases, Device Templates is titled Device.

3. Click Create Template. From the Create Template drop-down list, choose From Feature Template.

4. From the Device Model drop-down list, choose the type of device for which you are creating the template.

5. Click Service VPN. Under Additional VPN Templates, click PIM.

6. From the PIM drop-down list, click Create Template. The PIM template form is displayed. The top of the form contains fields for naming the template, and the bottom contains fields for defining PIM parameters.

7. In the Template Name field, enter a name containing up to 128 alphanumeric characters. In the Template Description field, enter a description containing 2048 alphanumeric characters.

8. Click Basic Configuration and configure SSM – On/Off.

9. Configure access list (if already defined), RP option (Auto-RP or static RP), RP Announce settings and configure the interface name on the service side.

   Save feature template and attach feature template to a device template.

   When you first open a feature template, for each parameter that has a default value, the scope is set to Default (indicated by a check mark), and the default setting or value is shown. To change the default or to enter a value, click the scope drop-down list to the left of the parameter field and select the value.

   Parameter Scope	Scope Description
   Device Specific (indicated by a host icon)	Use a device-specific value for the parameter. For device-specific parameters, you cannot enter a value in the feature template. You enter the value when you attach a Cisco IOS XE Catalyst SD-WAN device to a device template. When you click Device Specific, the Enter Key box opens. This box displays a key, which is a unique string that identifies the parameter in a CSV file that you create. This file is an Excel spreadsheet that contains one column for each key. You upload the CSV file when you attach a Cisco IOS XE Catalyst SD-WAN device to a device template. To change the default key, type a new string and move the cursor out of the Enter Key box. Examples of device-specific parameters are system IP address, hostname, GPS location, and site ID.
   Global	Enter a value for the parameter, and apply that value to all devices. Examples of parameters that you might apply globally to a group of devices are DNS server, syslog server, and interface MTUs.

   To configure PIM, click Basic Configuration and configure the following parameters. Parameters marked with an asterisk are required to configure PIM.

   Table 6. Basic Configuration

   Parameter Name	Description
   Auto-RP	Click On to enable Auto-RP to enable reception of PIM group-to-RP mapping updates. This will enable reception on the Auto-RP multicast group, 224.0.1.39 and 224.0.1.40. By default, Auto-RP is disabled.
   Auto-RP RP Announce	Click On to enable transmission of Auto-RP multicast messages. By default, RP Announce is disabled.
   Auto-RP RP Discovery	Click On to enable Auto-RP automatic discovery of rendezvous points (RPs) in the PIM network so that the router can serve as an Auto-RP mapping agent. An Auto-RP mapping will receive all the RPs and their respective multicast groups and advertise consistent group-to-RP mapping updates. By default, RP Discovery is disabled.
   Static-RP	Specify the IP address of a rendezvous point (RP).
   SPT Threshold	Specify the traffic rate, in kbps, at which to switch from the shared tree to the shortest-path tree (SPT). Configuring this value forces traffic to remain on the shared tree and travel via the RP instead of via the SPT.
   Interface	Specify the source interface for Auto-RP RP Announcements or RP Discovery messages.
   Scope	Specify the IP header Time-to-Live (TTL) for Auto-RP RP Announcements or RP Discovery messages.

   To save the feature template, click Save.

   If the router is just a multicast replicator and is not part of a local network that contains either multicast sources or receivers, you do not need to configure any PIM interfaces. The replicator learns the locations of multicast sources and receivers from the OMP messages it exchanges with the Cisco Catalyst SD-WAN Controller. These control plane messages are exchanged in the transport VPN (VPN 0). Similarly, other Cisco IOS XE Catalyst SD-WAN devices discover replicators dynamically, through OMP messages from the Cisco Catalyst SD-WAN Controller.

   To configure PIM interfaces, click Interface. Then click Add New Interface and configure the following parameters:

   Parameter Name	Description
   Name	Enter the name of an interface that participates in the PIM domain, in the format ge slot /port .
   Hello Interval	Specify how often the interface sends PIM hello messages. Hello messages advertise that PIM is enabled on the router. Range: 1 through 3600 seconds Default: 30 seconds
   Join/Prune Interval	Specify how often PIM multicast traffic can join or be removed from a rendezvous point tree (RPT) or shortest-path tree (SPT). Cisco IOS XE Catalyst SD-WAN send join and prune messages to their upstream RPF neighbor. Range: 0 through 600 seconds Default: 60 seconds

   To edit an interface, click the pencil icon to the right of the entry.

   To delete an interface, click the trash icon to the right of the entry.

   To save the feature template, click Save.
