Subject: Re: [nsp] known networks for broadcast ping attacks

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,

Spoofing is forging a packet's source address. Source routing is including information in the packet that tells the route the packet should take to get to its destination.
