Unless you put something in your network not to route rfc1918 space -it will route. There is nothing technical that prevents it from routing.
You should drop rfc1918 space exiting out of the wan of any device that has that space behind it if you are NATing. You should drop it out your edge as well to your upstream (only allow your prefixes/peer ips out). I've actually pinged something I shouldn't have been able to ping wondering wth and then doing a trace to find that my upstream was not dropping 1918. Was a tier 2 east cost provider.
