PIM Sparse
23
If the interface is on the border of the PIM Sparse domain, you also must enter the following
command.
BigIron RX(config-if-e10000-2/2)# ip pim border
Syntax: [no] ip pim border
NOTE
You cannot configure a Brocade 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 BigIron RX as a candidate PIM Sparse Bootstrap router (BSR) and
candidate PIM Sparse Rendezvous Point (RP).
NOTE
It is possible to configure the BigIron RX as only a candidate BSR or RP, but Brocade recommends
that you configure the same interface on the same BigIron RX as both a BSR and an RP.
This section presents how to configure BSRs. Refer to “Configuring RPs” on page 609 for
instructions on how to configure RPs.
To configure the BigIron RX as a candidate BSR, enter commands such as the following.
BigIron RX(config)# router pim
BigIron RX(config-pim-router)# bsr-candidate ethernet 2/2 30 255
B SR 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 <slot>/<portnum> | loopback <num> | ve <num>
<hash-mask-length> [ <priority> ]
The ethernet <slot> / <portnum> | loopback <num> | ve <num> parameter specifies the interface.
The BigIron RX will advertise the specified interface’s IP address 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.
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.
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 BigIron RX as a candidate RP.
BigIron RX(config-pim-router)# rp-candidate ethernet 2/2
Syntax: [no] rp-candidate ethernet <slot> / <portnum> | loopback <num> | ve <num>
