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 bandwidth waste caused by frequent message exchanges between C-RPs and the BSR.
Restrictions and guidelines
The static RP configuration must be the same on all devices in the IPv6 BIDIR-PIM domain.
In a BIDIR-PIM 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.
You can specify an unused IP address for a static RP. This address must be on the same subnet with the link on which the static RP is configured. For example, if the IP addresses of the interfaces at the two ends of a link are 10.1.1.1/24 and 10.1.1.2/24, you can specify the interface with IP address 10.1.1.100/24 as a static RP. As a result, the link becomes an RPL.
