I hate to type (besides, the more I type, the more mistakes I make), so I
offer this:

I have several routers on the Internet (Linux systems whos job is routing)
and I find I have to add/del/change routes on a fairly frequent basis.  I
use:

route add -net xxx.xxx.xxx.xxx/yy gw abc.def.ghi.jkl
if I have to delete the route, I find I don't need the "gw
abc.def.ghi.jkl" part unless I have already added the substitute route
first, then I need to remove it specifically with the gateway.

Guess what I really need to do is start using zebra, except that several
of the routes go to clients' Windoze boxes for Internet sharing, and of
course those useless POS' would have no clue about routing daemons.  In
fact, what they do is either "bridging" (a la M$, which means it's not
what we know as true bridging) or proxying, but not true routing.  So I
guess I'll be adding/deleting static routes for the forseeable future.

Ciao,
