Ok, I am having issues...
What does a router do when it receives a generic data packet (NOT AN ICMP packet) and has not route and no default route???
Does it
A) drop the packet
OR
b) drop the packet AND send a icmp (destination unreachable message) back to the source?
I can't figure out which one of these is true????
Im taking the test in 4 hours.... can someone answer quick before then?

B.
It will Send you an ICMP message type 3 and a 0 or 1 erro code and drop the packet.
ICMP Message Type 3 means Destination Unreachable.
Error Code 0 means Net Unreachable.
Error Code 1 means Host Unreachable.
