Configuring PIM Sparse Mode (NSM Procedure)

To configure PIM sparse mode (PIM-SM) in a virtual router on a security device:

  1. Configure either a static route or a dynamic routing protocol, such as OSPF. (For information about configuring static routes, see Routing Table Entries Overview. For information about dynamic routing protocols, see Dynamic Routing Configuration Overview.)
  2. Create a security policy to pass unicast and multicast data traffic between zones. (For details on security policies, see the Network and Security Manager Administration Guide.
  3. Create and enable the PIM-SM routing instance in a virtual router.
  4. Select PIM-SM on interfaces that transmit multicast traffic.
  5. Configure a multicast rule to permit PIM-SM messages between zones. (For details on multicast rules, see the Network and Security Manager Administration Guide.

After you enable the PIM-SM routing instance in the virtual router and enable it on all applicable interfaces, you can optionally configure PIM-SM features such as the following:

To configure PIM-SM:

  1. In the NSM navigation tree, select Device Manager > Devices. Double-click the device icon to open the device configuration.
  2. Configure the virtual router for PIM-SM:
    • In the device navigation tree, select Network > Virtual Router.
    • Double-click the virtual router in which you are configuring a PIM-SM instance. The General Properties screen appears.
    • In the virtual router navigation tree, select Dynamic Routing Protocol.
    • Select Configure PIM-SM. PIM-SM configuration options now appear in the virtual router navigation tree under Dynamic Routing Protocol.
    • In the virtual router navigation tree, select Dynamic Routing Protocol > PIM-SM > Parameters. The Parameters configuration screen appears.
    • Select Enable in the main display area,
    • Click OK to save your changes to the virtual router.
  3. Configure the interface for PIM-SM:
    • In the device navigation tree, select Network > Interface.
    • Double-click the interface that transmits multicast traffic. The General Properties screen appears.
    • In the interface navigation tree, select Protocol, and then select the PIM-SM tab in the main display area.
    • Select Configure PIM-SM on Interface.
    • Select Enable PIM-SM.
    • Click OK to save your changes to the interface. Repeat Step 3 to enable PIM-SM on additional interfaces.
  4. Click OK to save your changes to the device configuration.
