我正在尝试通过以下命令在 Ubuntu 16.04 中添加新路线：
sudo route add -net 192.168.245.2 netmask 255.255.255.0 gw 192.168.0.200 enp2s0
但出现此错误：
route: netmask doesn't match route address
问题是什么？
我目前的路线配置：
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.0.2 0.0.0.0 UG 100 0 0 enp2s0
172.17.0.0 0.0.0.0 255.255.0.0 U 0 0 0 docker0
172.18.0.0 0.0.0.0 255.255.0.0 U 0 0 0 br-5486059fe8de
192.168.0.0 0.0.0.0 255.255.255.0 U 100 0 0 enp2s0
我的 ipconfig 是：

答案1
您要么更改 ip，要么更改掩码，即：
sudo route add -net 192.168.245.0 netmask 255.255.255.0 gw 192.168.0.200 enp2s0
或者
sudo route add -net 192.168.245.2 netmask 255.255.255.255 gw 192.168.0.200 enp2s0
