Hello! > route will be deleted after expire time 10 mins Sigh... I am sorry, it will never be _deleted_. When the thing becomes invisible, it does not mean it disappears. :-) Does not matter, I know how to do this correctly, just add the check for RTF_EXPIRES in gc collector, and never delete idle RTF_CACHE route, if RTF_EPRIRES is also set.
