PIM Sparse

Configuring global PIM Sparse parameters
To configure basic global PIM Sparse parameters, enter commands such as the following on each
Brocade device within the PIM Sparse domain.
Brocade(config)# router pim
Syntax: [no] router pim
NOTE
You do not need to globally enable IP multicast routing when configuring PIM Sparse.
The command in this example enables IP multicast routing, and enables the PIM Sparse mode of IP
multicast routing. The command does not configure the Brocade device as a candidate PIM Sparse
Bootstrap Router (BSR) and candidate Rendezvous Point (RP). You can configure a device as a PIM
Sparse device without configuring the Brocade device as a candidate BSR and RP. However, if you
do configure the device as one of these, it is recommended that you configure the device as both of
these. Refer to
“Configuring BSRs” .
Entering a [no] router pim command does the following:
• Disables PIM or DVMRP.
• Removes all configuration for PIM multicast on a Brocade device (router pim level) only.
Enabling PIM Sparse for a specified VRF
To enable PIM for the VRF named “blue”, use the following commands.
Brocade(config)# router pim vrf blue
Syntax: [no] router pim [ vrf vrf-name ]
The vrf parameter allows you to configure PIM (PIM-DM and PIM-SM) on the virtual routing instance
(VRF) specified by the vrf-name variable. All PIM parameters available for the default router
instance are configurable for a VRF-based PIM instance.
The [no] router pim vrf command behaves in the following manner:
• 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.
Brocade(config)# interface ethernet 2/2
Brocade(config-if-e10000-2/2)# ip address 207.95.7.1 255.255.255.0
Brocade(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.
Brocade(config-if-e10000-2/2)# ip pim border
