How to make sure, on the same interface, to properly route traffic to the same subnet, based on availability of a gateway?
10.1.1.1/24 interface eth0/1 gateway 10.1.2.1 pref 10 metric 1 10.1.1.1/24 interface eth0/1 gateway 10.1.3.1 pref 20 metric 1
this usually means while accessing, for example,
10.1.1.50 it goes via
10.1.2.1, but the problem is, when
10.1.2.1 is down (cannot ping), it will not automatically goes to the second route (it does if using 2 interfaces and the first interface physically goes down).
