BGP best path selection
I need a confirmation on this. what if a router that are RR server, receives a route from its client but have better route than that. in my lab, it selected just the best route that it has and advertise it to other clients; taht is, it did not advertised the routes that have been received from the RR clients to other clients (based on the RR rule), just because it has the better route. is it a BGP normal behavior?
this can be right but has side effects; for example, suppose that RR server advertised the routes received from the RR clients to other clients beside the route that it had before, and this route had a better next-hop address?
