You can mix a list of unipath or multipath routes into alternative routes, see my docs. One of the alternative routes is used until it fails. If you need different algorithm you have to create script to handle it. > Is "weight 0" used for anything right now, or even possible? Weight 0 is not allowed, it will need changing too much code. If you can call ip route change, then you can call del+add and to apply the new routes. > Adrian Chung (adrian at enfusion-group dot com) > http://www.enfusion-group.com/~adrian > GPG Fingerprint: C620 C8EA 86BA 79CC 384C E7BE A10C 353B 919D 1A17 > [rogue.enfusion-group.com] up 134 days, 4:07, 4 users Regards -- Julian Anastasov <ja@xxxxxx>
