With the Embedded RP feature enabled, the router can resolve the RP address directly from the IPv6 

multicast group address of an IPv6 multicast packets. This RP can replace the statically configured RP 

or the RP dynamically calculated based on the BSR mechanism. Thus, the DR does not need to know 

the RP address beforehand.  

Follow these steps to enable embedded RP:

Use the command...

Enable embedded RP 

embedded-rp [ acl6-number ] 

Optional 

By default, embedded RP is 
enabled for IPv6 multicast 
groups in the default embedded 
RP address scopes.  

 

The default embedded RP address scopes are FF7x::/12 and FFFx::/12. Here “x” refers to any legal 

address scope. For details of the scope field, see Multicast Overview of the IP Multicast Volume. 

 

To enable the BSR to distribute the RP-Set information within the IPv6 PIM-SM domain, C-RPs must 

periodically send C-RP-Adv messages to the BSR. The BSR learns the RP-Set information from the 

received messages, and encapsulates its own IPv6 address together with the RP-Set information in its 

bootstrap messages. The BSR then floods the bootstrap messages to all IPv6 routers in the network.  

Each C-RP encapsulates a timeout value in its C-RP-Adv messages. Upon receiving a C-RP-Adv 

message, the BSR obtains this timeout value and starts a C-RP timeout timer. If the BSR fails to hear a 

subsequent C-RP-Adv message from the C-RP when the timer times out, the BSR assumes the C-RP 

to have expired or become unreachable.  

The C-RP timers need to be configured on C-RP routers. 

Follow these steps to configure C-RP timers globally:
