With a little bit of awk, you can dump a routing table to a file, then
read the file back in. To dump:

#!/bin/sh
## The tail +3 skips the first two lines -- "Kernel IP routing
## table" and the column headers
route -n | tail +3 | awk '
$4 == "UH" {
    print "-host", $1, "metric", $5, "dev", $8
}

$4 == "U" {
    print "-net", $1, "metric", $5, "dev", $8
}

$4 == "UG" {
    print "default", "gw", $2, "metric", $5, "dev", $8
}
'
## End of script. copy, paste, chmod 700 (or whatever)


Run the script, redirecting the output to file, then you can
read the contents back in, something like:

#!/bin/sh
cat my_saved_routes | while read a b c d e f g
do
    route add $a $b $c $d $e $f $g
done
## End of script


Now the awk script could be refined quite a bit, but it should give you
a starting point from which to work with :-)

Enjoy,

Chris...
