The list of reachable C-RPs is also referred to as an RP set. To view the current RP set, use the
show ip pim group-map command. For example:
-> show ip pim group-map
Origin Group Address/Pref Length RP Address Mode Precedence
---------+---------------------------+-------------+-----+-----------
BSR 225.0.0.0/24 172.21.63.11 asm 192
BSR 225.0.0.0/24 214.0.0.7 asm 192
Static 232.0.0.0/8 ssm
For more information about these displays, see the “PIM Commands” chapter in the OmniSwitch AOS
Release 7 CLI Reference Guide.
Note. There is only one BSR per PIM-SM domain. This allows all PIM-SM routers in PIM-SM domain to
view the same list of reachable C-RPs.
Configuring Static RP Groups
A static RP group is used in the group-to-RP mapping algorithm. To specify a static RP group, use the
ip pim static-rp command. Be sure to enter a multicast group address, a corresponding group mask, and a
32-bit IP address for the static RP in the command line. For example:
-> ip pim static-rp 225.0.0.0/24 10.1.1.1 priority 10
This command entry maps all multicast groups 225.0.0.0/24 to the static RP 10.1.1.1 and specifies the
priority value to be used for the static RP configuration as 10. This priority value provides fine control
over which configuration is overridden by this static configuration. If the priority option has been defined,
a value of 65535 can be used to unset the priority.
You can also specify this static RP configuration to override the dynamically learned RP information for
the specified group using the override parameter. As specifying the priority value obsoletes the override
option, you can use either the priority or override parameter only.
Use the no form of this command to delete a static RP configuration.
-> no ip pim static-rp 225.0.0.0/24 10.1.1.1
