Configuring IP Multicast Protocols
December 2005 © Foundry Networks, Inc. 19 - 17
NOTE: You cannot configure a Foundry routing interface as a PMBR interface for PIM Sparse in the current
software release.
Configuring BSRs
In addition to the global and interface parameters in the sections above, you need to identify an interface on at
least one Layer 3 Switch as a candidate PIM Sparse Bootstrap router (BSR) and candidate PIM Sparse
Rendezvous Point (RP).
NOTE: It is possible to configure the Layer 3 Switch as only a candidate BSR or RP, but Foundry Networks
recommends that you configure the same interface on the same Layer 3 Switch as both a BSR and an RP.
This section presents how to configure BSRs. Refer to “Configuring RPs” on page 19-17 for instructions on how to
configure RPs.
To configure the Layer 3 Switch as a candidate BSR and RP, enter commands such as the following:
FastIron SuperX Router(config)# router pim
FastIron SuperX Router(config-pim-router)# bsr-candidate ethernet 2/2 30 255
BSR address: 207.95.7.1, hash mask length: 30, priority: 255
This command configures the PIM Sparse interface on port 2/2 as a BSR candidate, with a hash mask length of
30 and a priority of 255. The information shown in italics above is displayed by the CLI after you enter the
candidate BSR configuration command.
Syntax: [no] bsr-candidate ethernet [<slotnum>/]<portnum> | loopback <num> | ve <num>
<hash-mask-length> [<priority>]
The <slotnum> parameter is required on chassis devices.
The <portnum> | loopback <num> | ve <num> parameter specifies the interface. The Layer 3 Switch will
advertise the specified interface’s IP address as a candidate BSR.
• Enter ethernet [<slotnum>/] <portnum> for a physical interface (port).
• Enter ve <num> for a virtual interface.
• Enter loopback <num> for a loopback interface.
The <hash-mask-length> parameter specifies the number of bits in a group address that are significant when
calculating the group-to-RP mapping. You can specify a value from 1 – 32.
NOTE: Foundry Networks recommends you specify 30 for IP version 4 (IPv4) networks.
The <priority> specifies the BSR priority. You can specify a value from 0 – 255. When the election process for
BSR takes place, the candidate BSR with the highest priority becomes the BSR. The default is 0.
Configuring RPs
Enter a command such as the following to configure the Layer 3 Switch as a candidate RP:
FastIron SuperX Router(config-pim-router)# rp-candidate ethernet 2/2
Syntax: [no] rp-candidate ethernet [<slotnum>/]<portnum> | loopback <num> | ve <num>
The <slotnum> parameter is required on chassis devices.
The <portnum> | loopback <num> | ve <num> parameter specifies the interface. The Layer 3 Switch will
advertise the specified interface’s IP address as a candidate RP.
• Enter ethernet [<slotnum>/]<portnum> for a physical interface (port).
• Enter ve <num> for a virtual interface.
• Enter loopback <num> for a loopback interface.
