Configuring static RPs
About static RPs
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 caused by frequent message exchanges between C-RPs and the BSR.
Restrictions and guidelines
In the IPv6 PIM-SM domain, you can configure the same static RP for multiple IPv6 multicast groups by using the same RP address but different ACLs.
You do not need to enable IPv6 PIM for an interface to be configured as a static RP.
If you configure multiple static RPs for an IPv6 multicast group, only the static RP with the highest IPv6 address takes effect.
The static RP configuration must be the same on all devices in the IPv6 PIM-SM domain.
