router tables are a stationary woodworking machines in which a vertically oriented spindle of a woodworking router protrudes from the machine table and can be spun at speeds typically between 3000 and 24,000 rpm
excluding static routes (which are then usually advertised to other peers), routING tables are dynamically built and only exist in non-persistent memory.
having up to date backups of router configuration is another matter entirely
Doing the wrong thing to router table(s) is the network equivalent of "sudo rm -rf /".
