Configuring an RP
An RP can be manually configured or dynamically elected through the BSR mechanism. For a large IPv6
PIM network, static RP configuration is a tedious job. Generally, static RP configuration is just a backup
method for the dynamic RP election mechanism to enhance the robustness and operation manageability
of a multicast network.
IMPORTANT:
In an IPv6 PIM network, if both IPv6 PIM-SM and IPv6 BIDIR-PIM are enabled, do not confi

errors.
Configuring a static RP
If only one dynamic RP exists in a network, manually configuring a static RP can avoid communication
interruption because of single-point failures. It can also avoid frequent message exchange between C-RPs
and the BSR.
To enable a static RP to work normally, you must perform this configuration on all routers in the IPv6
PIM-SM domain and specify the same RP address.
Perform the following configuration on all the routers in the IPv6 PIM-SM domain.

No static RP by default.
Configuring a C-RP
In an IPv6 PIM-SM domain, you can configure routers that intend to become the RP as C-RPs. The BSR
collects the C-RP information by receiving the C-RP-Adv messages from C-RPs or auto-RP announcements
from other routers and organizes the information into an RP-set, which is flooded throughout the entire
network. Then, the other routers in the network calculate the mappings between specific group ranges
and the corresponding RPs based on the RP-set. H3C recommends that you configure C-RPs on backbone
routers.
