I think you want "netstat -rn". And, yes, I've already said, at least
twice, that I have 2 "default gateways"
I already said it is for the case where one path is down.
[egreshko@meimei ~]$ netstat -rn

This gives insufficient information about the usages of the "default gateways".
[egreshko@meimei ~]$ ip -4 route
default via 192.168.1.1 dev enp2s0 proto static metric 100
default via 192.168.2.5 dev wlp4s0 proto dhcp metric 600
192.168.1.0/24 dev enp2s0 proto kernel scope link src 192.168.1.18 metric 100
192.168.2.0/24 dev wlp4s0 proto kernel scope link src 192.168.2.127 metric 600
192.168.56.6 via 192.168.2.116 dev wlp4s0 proto static metric 600
192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1
is better for that since it shows the metric. Not that it would always be of interest but
with ip
you know if the route was configured via dhcp, is a static route, or was added by the
kernel.

not looking for that kind of "up"
I do not know what kind of "up" you mean then.

Again, I am looking for the configuration, not whether it
works or not.
OK, but you kept saying.... "I only want to know if the device is connected to the
gateway and the gateway is up." and even Samuel replied with "The only way to
tell if the gateway is up is to ping it or connect to it in some way."
So, I don't know what your "up" means.
