multiple static rp-address for multicast-pim/frr implementation

[nav60]

Hi,

Could you please guide me with the automatic switch between static addresses in the PIM module of FRR? I have seen similar functionality in the commercial vendor such as Fortinet multicast setting/configuration. It supports multiple static RP addresses and switches when the mapping agent message is received from the Cisco multicast network [It is my understanding and I am not sure about it because there is no other relevant message for static RP switching for edge multicast device]. However, PIM/FRR only allows a single RP address as the RP address for one group and configuration for an alternate rp address is not possible. Any suggestion or guidance, please.
