Hello Javier
In your case it looks like you’re using BGP between your CE and PE devices. Remember that when using BGP, you can advertise networks in two ways: redistribution and by using the network command. This is detailed in the following lesson:
In your configuration, I see you have used redistribution, and in particular, the redistribution of connected and static routes. This is why your 192.168.201.0/24 is propagated.
However, BGP will not advertise a default route using redistribution. It must be done using the default information-originate command that you correctly realized will solve your problem. The reason it must be implemented in this way is detailed in the following post:
I hope this has been helpful!
