Hi all, I've got a question about how OpenBSD deals with routes and interfaces that are considerd 'down'. I've noticed that when an interface in OpenBSD is down the route to that interface will remain in the routing table and is also not flagged with R(eject). The route stays exactly the same wheter the device is up or down.
In Linux (and I have no idea wheter this is a good idea or not) the route of the downed interface is removed. Is the above behavior normal? WHat should I do if I don't want to route traffic to downed interfaces (like backup CARP interfaces). The reason why I'm asking is because I want to route traffic somewhere else with ifstated when a device goes in CARP backup mode (upstream uses ECMP routing). But because the device route of the downed interface (the interface being a CARP interface in backup mode in this scenario) stays in the routing table with priority 1 I can't override it. Kind regards, Jasper
