To remove an RP address, use the no ip pim rp-address ip-address [access-list-number] [override] 
global configuration command.

This example shows how to configure the address of the RP to 147.106.6.22 for multicast 
group 225.2.2.2 only:

Switch(config)# access-list 1 permit 225.2.2.2 0.0.0.0

Switch(config)# ip pim rp-address 147.106.6.22 1

Auto-RP uses IP multicast to automate the distribution of group-to-RP mappings to all Cisco routers and 
multilayer switches in a PIM network. It has these benefits:

It is easy to use multiple RPs within a network to serve different group ranges.

It provides load splitting among different RPs and arrangement of RPs according to the location of 
group participants. 

It avoids inconsistent, manual RP configurations on every router and multilayer switch in a PIM 
network, which can cause connectivity problems.

Follow these guidelines when configuring Auto-RP:

If you configure PIM in sparse mode or sparse-dense mode and do not configure Auto-RP, you must 
manually configure an RP as described in the 

.

If routed interfaces are configured in sparse mode, Auto-RP can still be used if all devices are 
configured with a manual RP address for the Auto-RP groups.

If routed interfaces are configured in sparse mode and you enter the ip pim autorp listener global 
configuration command, Auto-RP can still be used even if all devices are not configured with a 
manual RP address for the Auto-RP groups.

If you are setting up Auto-RP in a new internetwork, you do not need a default RP because you configure 
all the interfaces for sparse-dense mode. Follow the process described in the 

. However, omit Step 3 if you want to configure a 

PIM router as the RP for the local group.

This section contains some suggestions for the initial deployment of Auto-RP into an existing 
sparse-mode cloud to minimize disruption of the existing multicast infrastructure.
