Configuring PIM Sparse Mode (NSM Procedure)

Copyright © 2010, Juniper Networks, Inc.
To configure PIM sparse mode (PIM-SM) in a virtual router on a security device:
Configure either a static route or a dynamic routing protocol, such as OSPF. (For
1.
information about configuring static routes, see "Routing Table Entries Overview" on
page 305. For information about dynamic routing protocols, see "Dynamic Routing
Configuration Overview" on page 313.)
Create a security policy to pass unicast and multicast data traffic between zones.
2.
(For details on security policies, see the Network and Security Manager Administration
Guide.
Create and enable the PIM-SM routing instance in a virtual router.
3.
Select PIM-SM on interfaces that transmit multicast traffic.
4.
Configure a multicast rule to permit PIM-SM messages between zones. (For details
5.
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:
Use access lists to restrict the rendezvous points (RPs) and sources from which a
multicast group can receive traffic. You can also use access lists to restrict the multicast
groups for which the virtual router forwards PIM join-prune messages. First, create the
access lists, and then enter the access list IDs in the PIM-SM configuration screen of
the virtual router. The security device then uses the access lists to filter the PIM-SM
traffic.
Change the default parameters for each interface on which PIM-SM is enabled. When
you set parameters at this level, the parameters affect the specific interface only.
Configure a static RP for a particular zone, or use dynamic RP mappings and configure
a virtual router as a candidate rendezvous point (C-RP).
You can configure a virtual router to function as a proxy RP.
To configure PIM-SM:
In the NSM navigation tree, select Device Manager > Devices. Double-click the device
1.
icon to open the device configuration.
Configure the virtual router for PIM-SM:
2.
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.
