About routing

[a bv]

Hi,
Im new to the list and want to ask where are the routing information is stored

- when i setup rhel 5.2 using the setup program and make the ip
configuration of the interface
-add a route on the fly using route add bla bla (and will this records
will be deleted when rebooted the system?)
-and any other possibilities/information about routing releated.


I know that making a /etc/sysconfig/network-scripts/route-eth0
configuration file and restarting the network service is mentioned in
the web , im afraid of losing the information of the current routing
cause im reaching the servers shell from
those routes which the server is on an other place /building which i
can not go easily.

Regards
