What will happen if I add a route without joining a group

If it's a (S,G) route, as opposed to a (*,G) route which involves handling from SMCRoute at runtime. Then a route will be added in the kernel, and when matching multicast ingresses the inbound interface it will be routed to the outbound interface(s) listed in the route.
A multicast join is mostly only useful for LANs where switches with IGMP snooping exist and you cannot configure a static multicast router port on.
