•

Entering the router pim vrf command to enable PIM does not require a software reload.

•

Entering a no router pim vrf command removes all configuration for PIM multicast on the
specified VRF.

Configuring PIM interface parameters

After you enable IP multicast routing and PIM Sparse at the global level, you must enable it on the
individual interfaces connected to the PIM Sparse network.

To enable PIM Sparse mode on an interface, enter commands such as the following.

device(config)# interface ethernet 2/2

device(config-if-e10000-2/2)# ip address 207.95.7.1 255.255.255.0

device(config-if-e10000-2/2)# ip pim-sparse

Syntax: [no] ip pim-sparse

The commands in this example add an IP interface to port 2/2, then enable PIM Sparse on the
interface.

If the interface is on the border of the PIM Sparse domain, you also must enter the following
command.

device(config-if-e10000-2/2)# ip pim border

Syntax: [no] ip pim border

Configuring BSRs

In addition to the global and interface parameters described in the previous sections, you need to
identify an interface on at least one device as a candidate PIM Sparse Bootstrap router (BSR) and
candidate PIM Sparse Rendezvous Point (RP).

NOTE
It is possible to configure the device as only a candidate BSR or RP, but it is recommended that you
configure the same interface on the same device as both a BSR and an RP.

This section describes how to configure BSRs. Refer to the “Configuring RPs” section for instructions
on how to configure RPs.

To configure the device as a candidate BSR, enter commands such as the following.

Device(config)# router pim

Device(config-pim-router)# bsr-candidate ethernet 2/2 30 255

These commands configure the PIM Sparse interface on port 2/2 as a BSR candidate, with a hash
mask length of 30 and a priority of 255.

Syntax: [no] bsr-candidate ethernet slot / portnum | loopback num | ve numhash-mask-length [
priority ]

The ethernet slot / portnum, loopback num, and ve num parameters specify the interface. The device
will advertise the IP address of the specified interface as a candidate BSR.

•

Enter ethernet slot / portnum for a physical interface (port).

•

Enter ve num for a virtual interface.

•

Enter loopback num for a loopback interface.
