Unexpected behavior of static routes

[Michael McConnell]

Right, what you are doing is something I do all day long.

I’ve looked over my configs and the only thing I can see that might be missing related to kernel. 

protocol kernel {
export all;

Sorry I’m not more help, but I can tell you that is definitely not the expected behaviour.
