【Liunx】查看网关

A.通过ip命令

[root@server1 ~]# ip route show
default via 192.168.3.254 dev ens33 proto dhcp metric 100 
192.168.3.0/24 dev ens33 proto kernel scope link src 192.168.3.3 metric 100 
192.168.3.0/24 dev ens33 proto kernel scope link src 192.168.3.5 metric 100 
192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1 

default via 后面的就是网关：192.168.3.254

B.通过route命令

[root@server1 ~]# route -n
Kernel IP routing table

0.0.0.0         192.168.3.254   0.0.0.0         UG    100    0        0 ens33
192.168.3.0     0.0.0.0         255.255.255.0   U     100    0        0 ens33
192.168.3.0     0.0.0.0         255.255.255.0   U     100    0        0 ens33

C.通过netstat命令

[root@server1 ~]# netstat -rn
Kernel IP routing table

0.0.0.0         192.168.3.254   0.0.0.0         UG        0 0          0 ens33
