I have four routers, and on one of them I need to configure the access control list so that the routing table in it remains unchanged.
Are these rtrs in the same ospf area sharing the same topology database?
Regards keeping the route table the same do you mean you would like to accept the same current routes you are receiving and filter all future routes, or you would like to filter all routes and have just a default?
If you could elaborate on exactly what you want to filter and how the these ospf rtrs are connected would depend on how the filtering is applied.
