Interface or gateway monitoring

[lguiraud]

I'm looking for an option which will disable an interface if a remote gateway is not available.

This option exist for ipsec vpn (tunnel monitor) but I didn't find it for an L3 interface.

For exemple, I want to use an interface for outgoing traffic and a backup interface if the gateway of the first link is down.

It works fine if I shutdown the interface and if routing is configured but I'd like to have an automatic backup solution

If anyone have an idea.

Would policy based forwarding fit your need? Sounds pretty close.
