1. A router, the router comprising:
one or more processors; and
one or more computer-readable non-transitory storage media, the one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the router to perform operations comprising:
optimizing Multicast Virtual Private Network (MVPN) route exchange in a Software-Defined Wide Area Network (SD-WAN) environment;
dropping, using an Overlay Management Protocol (OMP) component, one or more Selective-Provider Multicast Service Interface (S-PMSI) messages received from an MVPN manager;
communicating a state of S-MPSI to the OMP component;
generating, by the OMP component, a Leaf Auto-Discovery (Leaf A-D) route based on a received (S, G) or (*, G) join; and
generating, by the OMP component, a Leaf A-D removal in the event that one or more routers within the SD-WAN environment withdraw from the (S, G) or (*, G) join.
