Brocade FastIron Ethernet Switch IP Multicast Configuration Guide - Manual (Page 99)

‐ Identify the Brocade device as a candidate PIM Sparse Bootstrap Router (BSR), if
applicable.
‐ Identify the Brocade device as a candidate PIM Sparse Rendezvous Point (RP), if
applicable.
‐ Specify the IP address of the RP (if you want to statically select the RP).
NOTE
It is recommended that you configure the same Brocade device as both the BSR and the RP.
Current limitations
The implementation of PIM Sparse in the current software release has the following limitations:
• PIM Sparse and regular PIM (dense mode) cannot be used on the same interface.
• You cannot configure or display PIM Sparse information using the Web Management Interface.
(You can display some general PIM information, but not specific PIM Sparse information.)
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.
Device(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 the “Configuring BSRs” section.
Entering a no router pim command does the following:
• Disables PIM.
• 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.
Device(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:
