Configuring an RP
An RP can provide services for multiple or all multicast groups. However, only one RP can forward
multicast traffic for a multicast group at a time.
An RP can be manually configured or dynamically elected through the BSR mechanism. For a
large-scaled 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 a 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. The static RP configuration must be the same on
all routers in the PIM-SM domain.

Configuring a C-RP
IMPORTANT:
W
hen you configure a C-RP, reserve a relatively large bandwidth between the C-RP and other devices in
the PIM-SM domain.
In a PIM-SM domain, if you want a router to become the RP, you can configure the router as a C-RP. HP
recommends that you configure C-RPs on backbone routers.
