ip route命令

执行下面命令,同样可以查看默认网关地址:

ip route show

输出示例:

192.168.2.0/24 dev wlan0  proto kernel  scope link  src 192.168.2.3  metric 2 
192.168.1.0/24 dev eth0  proto kernel  scope link  src 192.168.1.254  metric 1 
192.168.122.0/24 dev virbr0  proto kernel  scope link  src 192.168.122.1 
169.254.0.0/16 dev wlan0  scope link  metric 1000 
default via 192.168.2.1 dev wlan0  proto static
在Ubuntu Linux上如何查看默认网关

如何查看Ubuntu Linux上默认网关IP地址?

解决方案

使用route或ip命令获取Ubuntu Linux的默认路由表。

route -n

输出示例:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.2.0     0.0.0.0         255.255.255.0   U     2      0        0 wlan0
192.168.1.0     0.0.0.0         255.255.255.0   U     1      0        0 eth0
192.168.122.0   0.0.0.0         255.255.255.0   U     0      0        0 virbr0
169.254.0.0     0.0.0.0         255.255.0.0     U     1000   0        0 wlan0
0.0.0.0         192.168.2.1     0.0.0.0         UG    0      0        0 wlan0

192.168.2.1是默认网关。

输出示例:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.2.0     *               255.255.255.0   U     2      0        0 wlan0
