Network is unreachable - CentOS
forums.centos.org › viewtopicFeb 16, 2015 · The only time you would get a network is unreachable is if you tried to create a route that was not accessible directly from your subnet. So with your interface having 192.168.250.98/24. ip ro add default via 192.168.250.1 <- works. ip ro add 8.8.8.8 via 192.168.250.250 <- works. ip ro add 8.8.8.9 via 192.168.251.1 <- network is unreachable.
