Configuring PIM-SM on the Router

Global Configuration Context for Supporting PIM-SM

Before configuring specific PIM-SM settings, it is necessary to enable IP
routing, IP multicast-routing, an IP routing protocol, and PIM in the global
configuration context. Also, if the router operates as an edge router for any
end points (receivers) expected to join multicast groups, then it is also
necessary to enable IGMP on the VLANs supporting such receivers.

Global Configuration Context Commands

Note

PIM-SM operation requires an IP routing protocol enabled on the router. You
can use RIP, OSPF, and/or static routing. The examples in this section use RIP.
For more on these topics, refer to 5 in this guide.

Syntax: [no] ip routing

Enables IP routing on the router. The

no form of the command

disables IP routing. Note that before disabling IP routing, it
is necessary to disable all other IP routing protocols on the
router. (Default: Disabled)

Syntax: [no] ip multicast-routing

Enables or disables IP multicast routing on the router. IP
routing must be enabled first. Note that router PIM must be
disabled before disabling IP multicast routing. (Default: Dis­
abled)

Syntax: [no] router < ospf | rip >

[no] ip route < ip-addr/mask-len > [< ip-addr | vlan | reject | blackhole >]

These commands are the options for the IP routing protocol
required to support PIM operation. For more on these options,
refer to the chapter titled “IP Routing Features” in this guide.

Syntax: [no] router pim

Enables PIM at the global level and puts the CLI into the PIM
context level. Executing the

no form of the command at the

global level disables PIM. IP routing must be enabled before
enabling PIM. (Default: Disabled.)
