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