1793BEnabling embedded RP
When the embedded RP feature is 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.
The default embedded RP address scopes are FF7x::/12 and FFFx::/12. Here "x" refers to any legal
address scope. For more information about the Scope field, see "Multicast overview."
Perform this configuration on all routers in the IPv6 PIM-SM domain.
To enable embedded RP:
Ste
p
Command Remarks
1418. Enter system view. system-view N/A
1419. Enter IPv6 PIM
view.
pim ipv6 N/A
1420. 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.
1794BConfiguring C-RP timers globally
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. 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 obtain 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.
You must configure the C-RP timers on C-RP routers.
To configure C-RP timers globally:

Command Remarks
1421. Enter system view. system-view N/A
1422. Enter IPv6 PIM view.
pim ipv6 N/A
1423. Configure the C-RP-Adv
interval.
c-rp advertisement-interval interval
Optional.
60 seconds by default.
1424. Configure C-RP timeout
timer.
c-rp holdtime interval
Optional.
150 seconds by default.

PIM timers."
