Enabling embedded RP
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.
Perform this configuration on all routers in the IPv6 PIM-SM domain.
To enable embedded RP:
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Enable embedded RP.
NOTE:
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
Configuring 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 message. Upon receiving this 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.
Perform this configuration on C-RP routers.
To configure C-RP timers globally:
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure the C-RP-Adv
interval.
4. Configure C-RP timeout time.
For more information about the configuration of other timers in IPv6 PIM-SM, see
