PIM Sparse

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 “Configuring RPs” for instructions on how to
configure RPs.
To configure the device as a candidate BSR, enter commands such as the following.
Brocade(config)# router pim
Brocade(config-pim-router)# bsr-candidate ethernet 2/2 30 255
BSR address: 207.95.7.1, hash mask length: 30, priority: 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. 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 | tunnel num | ve num
hash-mask-length [priority]
The ethernet slot/portnum | loopback num | 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.
Enter tunnel num for a GRE tunnel interface to be configured. The GRE tunnel interface is
enabled under the router PIM configuration.
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
it is recommended that 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 device as a candidate RP.
Brocade(config-pim-router)# rp-candidate ethernet 2/2
Syntax: [no] rp-candidate ethernet slot/portnum | loopback num | tunnel num | ve num
The ethernet slot/portnum | loopback num | ve num parameters specify the interface. The device
will advertise the IP address of the specified interface as a candidate RP.
Enter ethernet slot/portnum for a physical interface (port).
