I think you had better get some help before you break your network!

In the CLI, use the command:
show route 192.0.2.0/24
Hit ? for options such as exact, detail, etc.

Whoever that person is that said something about "use next-hop-self"
in this context, either you misunderstood them, or you shouldn't
listen to them anymore.  That has nothing to do with looking to see if
your router knows about a route.
