Route Command (now ip route)

2016 - updated Jun 2017

— The route command has now been replaced. The command was deprecated some time ago, but continued to be used. The replacement is part of the IP command set.

Pre CentOS 7 you can still use route, but as of v7 the IP command should be used.

  ip route
  
  
  default via 192.168.27.254 dev enp4s0f0  proto static  metric 100
  10.0.0.0/8 dev ens513f0  proto kernel  scope link  src 10.0.222.2  metric 100
  11.0.0.0/8 dev ens513f2  proto kernel  scope link  src 11.0.222.4  metric 100
  192.168.27.0/24 dev enp4s0f0  proto kernel  scope link  src 192.168.27.222  metric 100




The route command allows dynamic setting of a route from the command line, however using route without any parameters will show the currently configured routes.

Raspbian

Raspbian Jessie on a Raspberry Pi 3 (LAN connected only, no wifi or bluetooth)

route

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         137.58.71.254   0.0.0.0         UG    202    0        0 eth0
137.58.68.0     *               255.255.252.0   U     202    0        0 eth0

Here we can see the default gateway is 137.58.71.254 on eth0
