This script will *ATTEMPT* to either save, restore or flush your routing rules & policies.
It comes with NO guarantees. Use at Your OWN risks.
You should use '-test' first, and look carefully at the output. 
This'll show what would be done in normal mode.
See also '-help' for command lines arguments syntax.

If you want to exclude some tables/priorities from beeing processed, check the '-exclude-prio-list' and '-exclude-name-list' command line options.
(Note also that all lines in your rt_tables starting with '#' are treated as comments, and thus, ignored.)

I am currently using this script on several servers, using different iproute settings 
(multipath routing, fwmark, realms, nat, tos...) so far, without problem.
Please report any bug or feedbacks to Vincent DOT Jaussaud AT kelkoo DOT net

Enjoy !
