Re: [Lcdp-ccna] Static route challenge

[Geoffrey R. <geo...@zi...>]

Grant's answered this pretty thoroughly.  Static routes can be made to
routers on stub networks because they're on the end.  They will not
be routing packets through to anywhere else.  They are the end of the line.

I seem to remember that static routing are more efficient than
dynamic routing and there is a privacy thing as well if it matters.
