PIM Configuration Using the CLI

The switch supports two modes of Protocol Independent Multicast (PIM): Sparse Mode (SM) and Source Specific Multicast (SSM).

  • PIM-SM supports multicast groups spread out across large areas of a company or the Internet.

  • PIM-SSM optimizes PIM-SM by simplifying the many-to-many model (servers-to-receivers).

The spbm-config-mode boot flag must be disabled before you can configure PIM or IGMP. To verify the setting, enter show boot config flags in Privileged EXEC mode.

Before you begin

For an IPv4 PIM configuration using the CLI:

  • Configure an IPv4 interface.

    For more information, see IP routing configuration using the CLI.

  • Configure a unicast protocol, for example, Routing Information Protocol (RIP) or Open Shortest Path First (OSPF), globally and on the interfaces where you want to configure PIM-SM.

    For more information about RIP, see RIP configuration using CLI. For more information about OSPF, see OSPF configuration using CLI.

  • Enable PIM-SM globally.

  • Enable PIM-SM on individual interfaces.

  • You must first configure and enable PIM on an IP interface, which can be circuitless, before you can utilize that interface as a candidate rendezvous point (RP). To configure PIM-SM RP for an IP interface, see Configuring a candidate rendezvous point.

  • Configure one or more bootstrap routers (BSR) to propagate RP information to all switches in the network.

For an IPv6 PIM configuration using the CLI:

  • Configure an IPv6 interface.

    For more information, see Configure an IPv6 Interface.

  • Configure an IPv6 unicast protocol, for example, Routing Information Protocol Next Generation (RIPng) or Open Shortest Path First Version 3 (OSPFv3), globally and on the interfaces where you want to configure PIM.

    For more information about RIPng, see RIPng Configuration using CLI. For more information about OSPFv3, see OSPFv3 Configuration using CLI.

  • Enable IPv6 PIM-SM globally

  • Enable IPv6 PIM-SM on individual interfaces.
