Hi Wang,
Thank for your answer. May you explain how to do that?
I think this should work.
The general idea would be:
default via 192.168.0.1 dev wlan0 src 192.168.0.12 metric 300
default via 192.168.1.1 dev eth0 src 192.168.1.42 metric 200
where the route with the lowest metric is used. If it disappears, the
remaining route is used instead.
You should be able to do that on LEDE/OpenWRT, see the metric option here:
https://wiki.openwrt.org/doc/uci/network#ipv4_routes
The problem is that, in your case, it probably won't work, because:
1) you mentioned that the route doesn't go away when the interface goes
down (which might or might not be a bug)
2) if both gateways are in the same subnet, chances are you're screwed up
anyway, because the kernel will only do ARP on one of your interface,
for both routes. I'd be interested to know if this is not the case.
arp-filter can fix #2.
Thanks,
Ben
