When I type "no ip source route" on a Cisco, what exactly is that doing
for me?  Is it just disallowing the router itself to generate
source-routed packets or is it saying sink all source-routed packets?
All this talk of spoofing is getting me a bit confused.  What exactly is
the difference between source-routing and spoofing?

Just trying to understand a bit more,
