I'm testing a Teltonika RUTXR1 for autofailover between the wiredwan and the mobile circuit (using l2tp).
The wired connecting is using BGP to connect to our core and is pulling a default route. The thought is if the wired connection drops or is not getting a response that the default route get's removed as BGP has dropped and the Teltonoka will use the backup route (with a higher metric) out of the mobile (l2tp) circuit.
However even if I make the WAN unresponsive the route will not get removed from the routing table? It appears as long as the WAN has a configuration that it generates a default route out of that interface whether it's working or not.
I've also tried enabling failover in services to ping out of the WAN, thinking if it doesn't get a response out of that then surely it will remove it's default route. It doesn't. It marks it as 'offline' in the Failover section but when I check the routing table the default route is still there.
Is this a bug in the GUI or is it simply not possible? It seems crazy that you are forced to have a default route when you setup the WAN interface?
