To configure a single static RP, perform this task:
Command or Action
Step 1
Switch> enable
Step 2
Switch# configure terminal
Step 3
Switch(config)# ip multicast-routing
Step 4
Switch(config)# interface type number
Step 5
Switch(config-if)# ip pim [sparse-mode |
sparse-dense-mode]
Step 6
Repeat Steps 4 and 5 on every interface that uses IP
multicast.
Step 7
Switch(config-if)# exit
Step 8
Switch(config)# ip pim rp-address rp-address
[access-list] [override]
Step 9
Switch(config)# end
Step 10
Switch# show ip pim rp [mapping] [rp-address]
Step 11
Switch# show ip igmp groups [group-name |
group-address | interface-type
interface-number] [detail]
Step 12
Switch# show ip mroute [group-address |
group-name] [source-address | source-name]
[interface-type interface-number] [summary]
[count] [active kbps]
OL_28731-01
Purpose
Enables privileged EXEC mode.
Enters global configuration mode.
Enables IP multicast routing.
Selects an interface that is connected to hosts on which PIM
can be enabled.
Enables PIM on an interface. You must use sparse mode.
—
Returns to global configuration mode.
Configures the address of a PIM RP for a particular group.
Perform this step on any router.
•
The access-list argument specifies the number or name
•
of an access list that defines for which multicast groups
the RP should be used.
The override keyword specifies that if there is a
•
conflict between the RP configured with this command
and one learned by Auto-RP, the RP configured with
this command prevails.
Ends the current configuration session and returns to EXEC
mode.
(Optional) Displays RPs known in the network and shows
how the router learned about each RP.
(Optional) Displays the multicast groups having receivers
that are directly connected to the router and that were
learned through IGMP.
A receiver must be active on the network at the time
•
that this command is issued to ensure that receiver
information is present on the resulting display.
(Optional) Displays the contents of the IP multicast routing
(mroute) table.
