I've had a strange problem with ospf, the client 1 connects to my network and creates a route to the ip of it, after he disconnects the route it remained there, then when client 2 connects to the ip that was being used by 1 client he did not surf because the old routes were not broken, anyone know a way to solve this problem, or at least I can delete the routes that are no longer in use?? thank you all for PLEASE NOTE.

version? routing or routing-test? please post '/ip route print' when route is not removed

I was using 3:27 and 3:28 versions, and only routing, the route was created and it was not removed after the ips are disconnected, updated the router to 3.28 and the unused routes have been removed, until the time gave no further problems, I will continue to watch here, if happens again I post here, thanks for the help =)
