Can I add routes to rt_tables by hand with the vi editor?
If I add a route to that file, it will be there if I reboot the box?

I am sure there are stupid questions but I can't find the answer into the
papers I have here.

Luis,

 : Can I add routes to rt_tables by hand with the vi editor?

/etc/iproute2/rt_tables contains a mapping of human names to routing table
numbers.  I call them table identifiers to table ids.  This file does not
contain routes.

 : If I add a route to that file, it will be there if I reboot the box?

If you wish to add static routes to the system at boot, you should be able
to use the system network initialization scripts and config files (e.g.,
redhat has a file /etc/sysconfig/static-routes).

Otherwise, you should write your own startup script or modify
/etc/rc.d/rc.local to include the routes you wish to add.

If you are using network address translation, you may find my NAT SysV
init scripts convenient:

Does that answer your question?
