RP or the RP dynamically calculated based on the BSR mechanism. Thus, the DR does not need to
know the RP address beforehand.
Perform this configuration on all routers in the IPv6 BIDIR-PIM domain.
To enable embedded RP:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter IPv6 PIM view.
pim ipv6
N/A
3.
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, where x refers
to any legal address scope. For more
information about the Scope field, see

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 must be configured on C-RP routers.
To configure C-RP timers globally:

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.
