route table explanation

Question

I'm a newbie. Recently I used the command ip route ls to print my route table. Here is the content:

111.211.3.192/26 dev wlan0 proto kernel scope link src 111.211.3.205 metric 2

I'm curious about the meaning of proto kernel and scope link.

Answer 1

I'm partially quoting the man page.

scope type is the scope of the destinations covered by the route prefix. scope link means that within the network segment of the device communication is allowed through this link. Towards other network segments routing should be used.

protocol type is the routing protocol identifier of this route. proto kernel means:

The route was installed by the kernel during autoconfiguration.

For more information, see:

• The man page that can be read by typing man ip in a terminal window.
• Several topics on Serverfault. Especially this on scope.
