Why My Static Routing Commands Don't Work?

I want to try routing on routers. Router does not show me my static routing commands. enter image description here

I used this static routing command on Router0
ip route 192.168.1.0 255.255.255.0 1.1.1.2

I used this static routing command on Router1
ip route 192.168.2.0 255.255.255.0 1.1.1.1

Router0

Router#
Router#conf ter
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#ip route 192.168.1.0 255.255.255.0 1.1.1.2
Router(config)#end

Solution

  • 192.168.1.0 255.255.255.0 is the same route as 192.168.1.0/24, and 192.168.2.0 255.255.255.0 is the same route as 192.168.2.0/24. Since these routes are already in the routing tables as "connected" which has a lower administrative distance (= 0) than "static" (= 1), the static route is not installed in the routing tables. (commingling this notation was a bad design decision by crisco imo)
