Configuring an RP

An RP can provide services for multiple or all IPv6 multicast groups. However, only one RP at a time
can forward IPv6 multicast traffic for an IPv6 multicast group.
An RP can be manually configured or dynamically elected through the BSR mechanism. For a
large-scaled IPv6 PIM network, configuring static RPs is a tedious job. Generally, static RPs are
backups for dynamic RPs to enhance the robustness and operational manageability on an IPv6
multicast network.
Configuring a static RP
If only one dynamic RP exists on a network, you can configure a static RP to avoid communication
interruption caused by single-point failures. The static RP can also avoid waste of bandwidth due to
frequent message exchange between C-RPs and the BSR.
You must configure the same static RP on all routers in the IPv6 PIM-SM domain.
To configure a static RP:

Configuring a C-RP
In an IPv6 PIM-SM domain, if you want a router to become the RP, you can configure the router as a
C-RP. As a best practice, configure C-RPs on backbone routers.
The C-RPs periodically send advertisement messages to the BSR, which collects RP-set
information for the RP election. You can configure the interval for sending the advertisement
messages.
The holdtime option in C-RP advertisement messages defines the C-RP lifetime for the advertising
C-RP. The BSR starts a holdtime timer for a C-RP after it receives an advertisement message. If the
BSR does not receive any advertisement message when the timer expires, it considers the C-RP
failed or unreachable.
A C-RP policy enables the BSR to filter C-RP advertisement messages by using an ACL that
specifies the packet source addresses and multicast group addresses. You must configure the same
C-RP policy on all C-BSRs in the IPv6 PIM-SM domain because every C-BSR might become the
BSR.
When you configure a C-RP, reserve a relatively large bandwidth between the C-RP and the other
devices in the IPv6 PIM-SM domain.
