If I have 20 routers that are part of the same MPLS L3 VPN and I need to let 10 routers ONLY know about some routes I have at a site that go over a Point to Point VPN, is there a way that I can redistribute these static routes into BGP and only have 10 routers know about them? I ask this because these static routes are subnets that overlap with some of the other 10 routers that DO NOT need to know about them, and if they do rather those sites going to each other for communication, they will come back to me for resources they do not need and traffic will be dropped and they will not be able to get what they really need to get to.

So I am redistributing ALL of the routes in the prefix list into BGP on the Nexus 5k which is iBGP peering with my CE.
I also have all of these same routes being blocked on my 5k from learning them via bgp.
I then go to my CE and apply what it pasted above...

Hi,
well, this solution is suitable for a small number of sites only.
But generally yes, you could apply some more sophisticated route-map with more prefix-lists "poisoning" a group of prefixes for each site (i.e., AS number) which should reject it.
Best regards,
