I read a few MPBGP MPLS 3 vpn lessons and now im a little bit confused. This is my situation.
With internal BGP, you need a full-mesh neighbor adjacency. The reason behind this is explained here:
To overcome this, you can use route reflectors:
So in your case, it depends on the configuration. If that router that is learning 240k routers is not a route reflector, it will not advertise those routes it learned through iBGP to your router at the top.
