Re: Null0 Route

{192.168.0.0/24}----[R1]----[R2]----{internet}

Imagine R1 having the default route to R2. Also, imagine R2 having the
route to 192.168.0.0/16 (which covers 192.168.0.0/24).

Packet arrives from {internet} to R2 with destination IP of
192.168.1.1. R2 looks up the routing table and decides packet needs to
go to R1. What will happen with this packet on R1?
