This example illustrates how to configure Auto-RP:
Switch> enable
Switch# configure terminal
Switch(config)# ip multicast-routing
Switch(config)# interface ethernet 1
Switch(config-if)# ip pim sparse-mode
Switch(config-if)# end
Switch(config)# ip pim autorp listener
Switch(config)# ip pim send-rp-announce loopback0 scope 31 group-list 5
Switch(config)# ip pim send-rp-discovery loopback 1 scope 31
Switch(config)# ip pim rp-announce-filter rp-list 1 group-list 2
Switch(config)# interface ethernet 1
Switch(config-if)# ip multicast boundary 10 filter-autorp
Switch(config-if)# end
Switch# show ip pim autorp

Purpose
Filters incoming Auto-RP announcement messages coming
from the RP.
• Perform this step on the RP router only.
• Two example access lists that apply to this step could
be:
access-list 1 permit 10.0.0.1
access-list 1 permit 10.0.0.2
access-list 2 permit 224.0.0.0 15.255.255.255
Selects an interface that is connected to hosts on which PIM
can be enabled.
Configures an administratively scoped boundary.
• Perform this step on the interfaces that are boundaries
to other routers.
The access list is not shown in this task.
•
• An access list entry that uses the deny keyword creates
a multicast boundary for packets that match that entry.
Returns to EXEC mode.
(Optional) Displays the Auto-RP information.
(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 Internet Group Management Protocol
(IGMP).
• A receiver must be active on the network at the time
that this command is issued to ensure the presence of
receiver information on the resulting display.
(Optional) Displays the contents of the IP multicast routing
(mroute) table.
