To do... Use the command... Remarks
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.
NOTE:
The default embedded RP address scopes are FF7x::/12 and FFFx::/12, where x refers to any legal
address scope. For more information about the Scope field, see the chapter “Multicast overview.”
Configuring C-RP timers globally
To enable the BSR to distribute the RP-Set information within the IPv6 BIDIR-PIM 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. After 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:

common timers .”
Configuring a BSR
An IPv6 BIDIR-PIM domain can have only one BSR, but must have at least one C-BSR. Any router can be
configured as a C-BSR. Elected from C-BSRs, the BSR collects and advertises RP information in the IPv6
BIDIR-PIM domain.
Configuring a C-BSR
C-BSRs must be configured on routers on the backbone network. When configuring a router as a C-BSR,
be sure to specify an IPv6 PIM-SM-enabled interface on the router. The BSR election process is as follows:
• Initially, every C-BSR assumes itself to be the BSR of the IPv6 BIDIR-PIM domain, and uses its
interface IPv6 address as the BSR address to send bootstrap messages.
