Configuring Auto-RP to Automate Group-to-RP Mappings
This task configures the Auto-RP mechanism to automate the distribution of group-to-RP mappings in your
network. In a network running Auto-RP, at least one router must operate as an RP candidate and another
router must operate as an RP mapping agent. The VRF interface on Cisco ASR 9000 Series Routers cannot
be an auto-rp candidate- rp.

Implementing Layer-3 Multicast Routing on Cisco IOS XR Software
Purpose
• If you specify a group-access-list-number value, you
must configure that access list using the ipv4 access-list
command.
(Optional) Allows backward compatibility on the RP that
uses old register checksum methodology.
Exits PIM configuration mode, and returns the router to the
source configuration mode.
(Optional) Enters access list configuration mode and
configures the RP access list.
• The access list called "rp-access" permits multicast
group 239.1.1.0 0.0.255.255.
(Optional) Permits multicast group 239.1.1.0 0.0.255.255
for the "rp-access" list.
The commands in Step 6, on page 196
Tip
on page 196 can be combined in one command string
like this: ipv4 access-list rp-access permit 239.1.1.0
0.0.255.255.
