Hi All,
One of my friends has come up with this
problem/question. What is the best way(s) for
redistribution between classful and classless?
I am also a bit confused on this, I have checked the
books and one of the way that they say is using static
routes, I am quite sure we cant use that one as static
routes till allowed cant be used(in the lab).
Particularly its the problem below. router r1 is able
to ping the other routes, and r2 being having rip is
not.
