Here’s a funny question for you to think about, take a look at the following picture:
The link above is a PPP connection and as you can see we have a mismatch in IP addresses. If you send a ping however it will still be succesfull, there are no routing protocols.
So the big question is…why does it work? I’ll give you the answer next week!
PS – Google is not your friend this time, see if you can find the answer yourself 🙂
